                                 PROXY STATEMENT
                     FOR THE ANNUAL MEETING OF STOCKHOLDERS
                          TO BE HELD ON APRIL 21, 2005

GENERAL

     The enclosed Proxy is solicited on behalf of the Board of Directors of
Silicon Laboratories Inc., a Delaware corporation, for use at the Annual Meeting
of Stockholders to be held on April 21, 2005 at 9:30 a.m. Central Time at the
Lady Bird Johnson Wildflower Center, 4801 La Crosse Avenue, Austin, Texas 78739,
or at any adjournment thereof. These proxy solicitation materials were mailed on
or about March 14, 2005 to all stockholders entitled to vote at the Annual
Meeting.

VOTING

     The specific proposals to be considered and acted upon at the Annual
Meeting are summarized in the accompanying notice and are described in more
detail in this Proxy Statement. On February 21, 2005, the record date for
determination of stockholders entitled to notice of and to vote at the Annual
Meeting, there were 52,697,222 shares of our common stock outstanding and no
shares of our preferred stock were outstanding. Each stockholder is entitled to
one vote for each share of common stock held by such stockholder on February 21,
2005. The presence, in person or by proxy, of the holders of a majority of our
shares entitled to vote is necessary to constitute a quorum at the Annual
Meeting or at any adjournment thereof. Stockholders may not cumulate votes in
the election of directors. The vote of a plurality of the shares of our common
stock present in person or represented by proxy at this meeting and entitled to
vote on the election of directors is necessary for the election of a director.
The nominees receiving the greatest number of votes at this meeting will be
elected to our Board of Directors, even if they receive less than a majority of
such shares.

     All votes will be tabulated by the inspector of election appointed for the
meeting, who will separately tabulate affirmative and negative votes,
abstentions and broker non-votes (i.e., a Proxy submitted by a broker or nominee
specifically indicating the lack of discretionary authority to vote on the
matter). Abstentions and broker non-votes will be counted as present for
purposes of determining a quorum for the transaction of business, but will not
be counted for purposes of determining whether each proposal has been approved.

PROXIES

     If the enclosed form of Proxy is properly signed and returned or you
properly follow the instructions for telephone or internet voting, the shares
represented thereby will be voted at the Annual Meeting in accordance with the
instructions specified thereon. If the Proxy does not specify how the shares
represented thereby are to be voted, the Proxy will be voted FOR the election of
the directors proposed by the Board of Directors unless the authority to vote
for the election of such directors is withheld and, if no contrary instructions
are given, the Proxy will be voted FOR the approval of the selection of Ernst &
Young LLP as our independent registered public accounting firm. You may revoke
or change your Proxy at any time before the Annual Meeting by filing a notice of
revocation or another signed Proxy with a later date with our Corporate
Secretary at our principal executive offices at 4635 Boston Lane, Austin, Texas
78735. You may also revoke your Proxy by attending the Annual Meeting and voting
in person.

SOLICITATION

     We will bear the entire cost of solicitation, including the preparation,
assembly, printing and mailing of this Proxy Statement, the Proxy and any
additional solicitation materials furnished to the stockholders. Copies of
solicitation materials will be furnished to brokerage houses, fiduciaries and
custodians holding in their names shares that are beneficially owned by others
so that they may forward this solicitation material to such beneficial owners.
In addition, we may reimburse such persons for their costs in forwarding the
solicitation materials to such beneficial owners. The original solicitation of
proxies by mail may be supplemented by a solicitation by telephone or other
means by directors, officers or employees. No additional compensation will be
paid to these individuals for any such services.


Except as described  above, we do not presently  intend to solicit Proxies other
than by mail.

DEADLINE FOR RECEIPT OF FUTURE STOCKHOLDER PROPOSALS

     Pursuant to Rule 14a-8 under the Securities Exchange Act of 1934,
stockholder proposals to be presented at our 2006 annual meeting of stockholders
and in our proxy statement and form of proxy relating to that meeting must be
received by us at our principal executive offices in Austin, Texas, addressed to
our Corporate Secretary, not later than November 14, 2005, the date which is 120
days prior to March 14, 2006. These proposals must comply with applicable
Delaware law, the rules and regulations promulgated by the Securities and
Exchange Commission and the procedures set forth in our bylaws. Pursuant to our
bylaws, stockholder proposals received after November 14, 2005 will be
considered untimely. Unless we receive notice in the manner specified in the
previous sentence, the proxy holders shall have discretionary authority to vote
for or against any such proposal presented at our 2006 annual meeting of
stockholders.

                   MATTERS TO BE CONSIDERED AT ANNUAL MEETING
                       PROPOSAL ONE: ELECTION OF DIRECTORS

GENERAL

     The Board of Directors is divided into three classes, designated Class I,
Class II and Class III. Each class is as nearly equal in size as practicable,
with staggered three-year terms. The term of office of the Class I directors,

Meeting. Messrs. Sooch, Wood, and Walker have been nominated to continue as
Class I Directors. The three directors elected as Class I Directors at the
Annual Meeting will serve for a term of three years expiring at the 2008 annual
meeting of stockholders, or until their successor(s) have been duly elected and
qualified or until their earlier death, resignation or removal.

     Each nominee for election has agreed to serve if elected, and management
has no reason to believe that the nominees will be unavailable to serve. In the
event a nominee is unable or declines to serve as a director at the time of the
Annual Meeting, the Proxies will be voted for any nominee who may be designated
by our present Board of Directors to fill the vacancy. Unless otherwise
instructed, the Proxy holders will vote the Proxies received by them FOR the

Directors recommended by stockholders and to determine the procedures with
respect to such stockholder recommendations. The Board of Directors has adopted
a written charter for the Nominating and Corporate Governance Committee, a
current copy of which is available on our internet website under the "Investor
Relations" page. Our internet website address is http://www.silabs.com. The

five meetings during fiscal 2004. The Nominating and Corporate Governance
Committee recommended, and the Board of Directors approved, the Corporate
Governance Policy which is attached as Exhibit B hereto.

DIRECTOR NOMINATION

     In evaluating potential director candidates, the Nominating and Corporate
Governance Committee considers the appropriate balance of experience, skills and
characteristics required of the Board of Directors and seeks to ensure that at
least a majority of the directors are independent under the applicable
Marketplace Rules of The NASDAQ Stock Market, Inc. The Nominating and Corporate
Governance Committee selects director nominees based on their personal and
professional integrity, depth and breadth of experience, ability to make
independent analytical inquiries, understanding of our business, willingness to
devote adequate attention and time to duties of the Board of Directors and such
other criteria as is deemed relevant by the Nominating and Corporate Governance
Committee. Silicon Laboratories believes that the backgrounds and qualifications
of the directors, considered as a group, should provide a diverse mix of
experience, knowledge and skills.

     In identifying potential director candidates, the Nominating and Corporate
Governance Committee relies on recommendations made by current directors and
officers. In addition, the Nominating and Corporate Governance Committee may
engage a third party search firm to identify and recommend potential candidates.
Finally, the Nominating and Corporate Governance Committee will consider
candidates recommended by stockholders.

     Any stockholder wishing to recommend a director candidate for consideration
by the Nominating and Corporate Governance Committee must provide written notice
not later than November 14, 2005 to the Corporate Secretary at our principal
executive offices located at 4635 Boston Lane, Austin, Texas 78735. Any such
notice should clearly indicate that it is a recommendation of a director
candidate by a stockholder and must set forth (i) the name, age, business
address and residence address of the recommended candidate, (ii) the principal
occupation or employment of such recommended candidate, (iii) the class and
number of shares of the corporation which are beneficially owned by such
recommended candidate, (iv) a description of all understandings or arrangements
between the stockholder and the recommended candidate and any other person or
persons pursuant to which the recommendations are to be made by the stockholder
and (v) any other information relating to such recommended candidate that is
required to be disclosed in solicitations of proxies for the election of
directors. In addition, such notice must contain (i) a representation that the
stockholder is a holder of record of stock of the corporation entitled to vote
at such meeting, (ii) the name and address, as they appear on the corporation's
books, of the stockholder proposing such nomination, (iii) the class and number
of shares of the corporation that are beneficially owned by such stockholder,
(iv) any material interest of the stockholder in such recommendation and (v) any
other information that is required to be provided by the stockholder pursuant to
Regulation 14A under the Securities Exchange Act of 1934, as amended, in such
stockholder's capacity as proponent of a stockholder proposal.

                                       6


Assuming that a stockholder recommendation contains the information required
above, the Nominating and Corporate Governance Committee will evaluate a
candidate recommended by a stockholder by following substantially the same
process, and applying substantially the same criteria, as for candidates
identified through other sources.

ATTENDANCE AT ANNUAL MEETINGS

     The Board of Directors encourages all directors to attend our annual
meetings of stockholders if practicable. All directors attended the annual
meeting of stockholders held on April 29, 2004.

STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS

     The Board of Directors maintains a process for stockholders to communicate
with the Board of Directors or with individual directors. Stockholders who wish
to communicate with the Board of Directors or with individual directors should
direct written correspondence to our Corporate Secretary at our principal
executive offices located at 4635 Boston Lane, Austin, Texas 78735. Any such
communication must contain (i) a representation that the stockholder is a holder
of record of stock of the corporation, (ii) the name and address, as they appear
on the corporation's books, of the stockholder sending such communication and
(iii) the class and number of shares of the corporation that are beneficially
owned by such stockholder. The Corporate Secretary will forward such
communications to the Board of Directors or the specified individual director to
whom the communication is directed unless such communication is deemed unduly
hostile, threatening, illegal or similarly inappropriate, in which case the
Corporate Secretary has the authority to discard the communication or to take
appropriate legal action regarding such communication.

CODE OF ETHICS

     Silicon Laboratories Inc. has adopted a Code of Business Conduct and Ethics
that applies to all officers, directors, employees and consultants. Our Code of

DIRECTOR COMPENSATION AND INDEMNIFICATION ARRANGEMENTS

     Non-employee directors receive option grants at periodic intervals under
the automatic option grant program of our 2000 Stock Incentive Plan. Under the
automatic option grant program, each non-employee director receives an initial
automatic option grant to purchase 30,000 shares of common stock on the date
such individual joins the Board of Directors. The initial automatic option
grants are immediately exercisable, vest in four equal successive annual
installments upon each additional year of service measured from the date of
grant, and have exercise prices equal to the fair market value as of the grant
date. In addition, on the date of each annual stockholders meeting, each
non-employee director who continues to serve as a non-employee director receives
an automatic annual option grant to purchase 5,000 shares of common stock,
provided such individual has served as a non-employee director for at least six
months. The annual automatic option grants are immediately exercisable, vest on
the first anniversary of the date of grant and have exercise prices equal to
fair market value as of the grant date. Under this program, on the date of our
2004 annual meeting of stockholders, Messrs. Bock, Cash, Enloe, Walker and Wood
each received an automatic annual option grant to purchase 5,000 shares of
common stock at an exercise price per share of $50.03. In addition, directors
are eligible to receive option grants under the discretionary option grant
program of the 2000 Stock Incentive Plan. During fiscal 2004, Messrs. Bock,
Cash, Enloe, Walker and Wood each received a discretionary option grant to
purchase 5,000 shares of common stock at an exercise price per share of $31.77.
During fiscal 2005, it is anticipated that each non-employee director that has
served for at least six months will receive a discretionary option grant in
December 2005 to purchase 5,000 shares of common stock in addition to any
automatic option grant.

                                       7


     During fiscal 2004, cash compensation consisted of (a) $25,000 per year for
each non-employee director, (b) an additional $20,000 per year for the Chairman
of the Audit Committee, and (c) an additional $5,000 per year for Audit
Committee members (excluding the Chairman). Messrs. Bock, Cash, Enloe, Walker
and Wood were each paid $25,000 during fiscal 2004 pursuant to the cash
compensation plan. Additionally, Mr. Bock was paid $20,000 for his service as
Chairman of the Audit Committee and Messrs. Enloe and Wood were each paid $5,000
for their services on the Audit Committee during fiscal 2004.

     During fiscal 2005, cash compensation is anticipated to consist of (a)
$25,000 per year for each non-employee director, (b) an additional $1,500 per
regular meeting of the Board of Directors for each non-employee director, (c) an
additional $20,000 per year for the Chairman of the Audit Committee, (d) an
additional $5,000 per year for Audit Committee members (excluding the Chairman),
(e) an additional $10,000 per year for the Chairman of the Compensation
Committee and (f) an additional $5,000 per year for the Chairman of the
Nominating and Corporate Governance Committee.

     Payments under the cash compensation plan are generally paid in equal
quarterly installments on the last day of each fiscal quarter. The cash
compensation plan was instituted, based on a review of compensation provided to
directors of similarly-situated companies, to provide incentives to retain and
to attract highly-qualified and motivated individuals to serve on our Board of
Directors.

     We reimburse directors for all reasonable out-of-pocket expenses incurred
in attending board and committee meetings.

     Our certificate of incorporation limits the personal liability of our
directors for breaches by them of their fiduciary duties. Our bylaws require us
to indemnify our directors to the fullest extent permitted by Delaware law. We
have also entered into indemnification agreements with all of our directors and
have purchased directors' and officers' liability insurance.

RECOMMENDATION OF THE BOARD OF DIRECTORS

     OUR BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE
ELECTION OF THE NOMINEES FOR CLASS I DIRECTORS LISTED ABOVE.

      PROPOSAL TWO: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED
                             PUBLIC ACCOUNTING FIRM

     Our Audit Committee has appointed the firm of Ernst & Young LLP to serve as
our independent registered public accounting firm for the fiscal year ending
December 31, 2005. Ernst & Young LLP has audited our financial statements since
our inception in 1996. A representative of Ernst & Young LLP is expected to be
present at the Annual Meeting, will have an opportunity to make a statement if
he or she so desires and will be available to respond to appropriate questions.

     The following table presents fees for professional services rendered by
Ernst & Young LLP for fiscal years 2004 and 2003:



                                       2004          2003
                                  -----------     ---------
                                            
  Audit fees ..................      $991,700      $239,700
  Audit-related fees ..........        14,900       135,600
  Tax fees ....................       116,300        69,700
  All other fees ..............            --            --
                                   ----------      --------
  Total .......................    $1,122,900      $445,000
                                   ----------      --------


     AUDIT FEES. Audit fees relate to services rendered in connection with the
audits of the annual financial statements and of management's assessment and the
operating effectiveness of internal control over financial reporting included in
our Form 10-K, the quarterly reviews of financial statements included in our
Forms 10-Q filings, Form S-8 consent procedures and statutory audits required
internationally.

     AUDIT-RELATED FEES. Audit-related fees include services for assurance and
other related services, such as consultations concerning financial accounting
and reporting matters and due diligence related to mergers and acquisitions.

     TAX FEES. Tax fees include services for tax compliance, research, and
technical tax advice.

     ALL OTHER FEES. All other fees include the aggregate fees for products and
services provided by Ernst & Young LLP that are not reported under "Audit Fees",
"Audit-Related Fees" or "Tax Fees". There were no other fees in 2004 or 2003.

     The Audit Committee is authorized by its charter to pre-approve all
auditing and permitted non-audit services to be performed by the Company's
independent registered public accounting firm. The Audit Committee reviews and
approves the independent registered public accounting firm's retention to audit
our financial statements, including the associated fee. The Audit Committee also
evaluates other known potential engagements of the independent registered public
accounting firm, including the scope of the proposed work and the proposed fees,
and approves or rejects each service, taking into account whether the services
are permissible under applicable law and the possible impact of each non-audit
service on the independent registered public accounting firm's independence from
management. At subsequent meetings, the Committee will receive updates on the
services actually provided by the independent registered public accounting firm,
and management may present additional services for approval. The Committee has
delegated to the Chairman of the Audit Committee the authority to evaluate and
approve engagements on behalf of the Committee in the event that a need arises
for pre-approval between Committee meetings. If the Chairman so approves any
such engagements, he will report that approval to the full Audit Committee at
its next meeting. During fiscal 2004, all such services were pre-approved in
accordance with the procedures described above.

     Our Audit Committee has reviewed the fees described above and believes that
such fees are compatible with maintaining the independence of Ernst & Young LLP.

     Stockholder ratification of the appointment of Ernst & Young LLP as our
independent registered public accounting firm is not required by our bylaws or
other applicable legal requirement. However, the appointment of Ernst & Young
LLP is being submitted to the stockholders for ratification. If the stockholders
fail to ratify the appointment, the Audit Committee will reconsider whether or
not to retain the firm. Even if the appointment is ratified, the Audit Committee
at its discretion may direct the appointment of a different independent
registered public accounting firm at any time during the year if it determines


                                       9


that such a change would be in the best interests of Silicon Laboratories and
its stockholders.

RECOMMENDATION OF THE BOARD OF DIRECTORS

     UPON THE RECOMMENDATION OF OUR AUDIT COMMITTEE, OUR BOARD OF DIRECTORS
RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF
ERNST & YOUNG LLP TO SERVE AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
FOR THE FISCAL YEAR ENDING DECEMBER 31, 2005.

                                 OTHER MATTERS

     We know of no other matters that will be presented for consideration at the
Annual Meeting. If any other matters properly come before the Annual Meeting, it

authority with respect to such other matters is granted by the execution of the

an independent audit of management's assessment and the operating effectiveness
of internal controls over financial reporting and for issuing a report thereon.
The Committee's responsibility is to monitor and oversee these processes.

     In this context, the Committee has met and held discussions with management
and the independent registered public accounting firm. Management represented to
the Committee that the Company's consolidated financial statements in the Annual
Report were prepared in accordance with accounting principles generally accepted
in the United States, and the Committee has reviewed and discussed the
consolidated financial statements in the Annual Report with management and the
independent registered public accounting firm. The Committee discussed with the
independent registered accounting firm matters required to be discussed by
Statement on Auditing Standards No. 61 (Communication with Audit Committees).

     The Company's independent registered public accounting firm also provided
to the Committee the written disclosures required by Independence Standards
Board Standard No. 1 (Independence Discussions with Audit Committees), and the
Committee discussed with the independent registered public accounting firm that
firm's independence. The Audit Committee reviewed non-audit services provided by
its independent registered public accounting firm for the last fiscal year, and
determined that those services are not incompatible with maintaining the
independent registered public accounting firm's independence.

     Based upon the Committee's discussion with management and the independent
registered public accounting firm and the Committee's review of the
representation of management and the reports of the independent registered
public accounting firm to the Committee, the Committee recommended that the
Board of Directors include the audited consolidated financial statements in the
Company's Annual Report on Form 10-K for the year ended January 1, 2005 filed
with the Securities and Exchange Commission.

     Submitted by the Audit Committee of the Board of Directors:

EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS

     The Compensation Committee of the Board of Directors, as Plan Administrator
of the 2000 Stock Incentive Plan, has the authority to provide for accelerated
vesting of the shares of our common stock subject to any outstanding options
held by any executive officer or any unvested share issuances actually held by
such individual, in connection with certain changes in control of us or the
subsequent termination of the officer's employment following the change in
control event.

     Our 2000 Stock Incentive Plan, which governs the options granted to the
named executive officers, includes the following change in control provisions,
which may result in the accelerated vesting of outstanding option grants and
stock issuances:

     o    In the event that we are acquired, each outstanding option under the
          discretionary option grant program, unless assumed or replaced by the
          successor or otherwise continued in effect, will immediately become
          exercisable for all the option shares, and all outstanding unvested
          shares will immediately vest, except to the extent our repurchase
          rights with respect to those shares are assigned to the successor or
          otherwise continued in effect.

     o    The plan administrator has the authority under the discretionary
          option grant program to provide that those options will automatically
          vest in full (i) upon an acquisition of the company, whether or not
          those options are assumed or replaced, (ii) upon a hostile change in
          control of the company effected through a tender offer for more than
          50% of our outstanding voting stock or by proxy contest for the
          election of board members, or (iii) in the event the individual's
          service is terminated, whether involuntarily or for good reason,
          within a designated period (not to exceed 18 months) following an
          acquisition in which those options are assumed or replaced or a
          hostile change in control.

     All outstanding restricted stock and stock options issued to our executive
officers named in the Summary Compensation Table of the Executive Compensation
section of this Proxy Statement will become fully exercisable and vested if (i)
a change-in-control occurs and such options and restricted stock are not assumed
or (ii) a change-in-control occurs and the officer is demoted, relocated or
terminated other than for misconduct within 18 months following such
change-in-control.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     None of our executive officers serves as a member of the Board of Directors
or Compensation Committee of any entity that has one or more of its executive
officers serving as a member of our Board of Directors or Compensation
Committee. No member of the Compensation Committee serves or has previously
served as one of our officers or employees.

             COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     It is the duty of the Compensation Committee to review and determine the
salaries and bonuses of our executive officers, including the Chief Executive
Officer, and to establish the general compensation policies for such
individuals. The Compensation Committee also has the sole and exclusive
authority to make discretionary option grants to our executive officers under
our 2000 Stock Incentive Plan.

     The Compensation Committee believes that the compensation programs for our
executive officers should reflect our performance and the value created for our
stockholders. In addition, the compensation programs should support our
short-term and long-term strategic goals and values and should reward individual
contribution to our success. We are engaged in a very competitive industry, and
our success depends upon our ability to attract and retain qualified executives
through the competitive compensation packages we offer to such individuals.

     GENERAL COMPENSATION POLICY. The Compensation Committee's policy is to
provide our executive officers with compensation opportunities that are based
upon their personal performance, our financial performance and their
contribution to that performance and which are competitive enough to attract and
retain highly skilled individuals.


                                       21


 Each executive officer's compensation package is
comprised of three elements: (i) base salary that is competitive with the
market and reflects individual performance; (ii) variable performance awards
payable in cash and tied to our achievement of financial performance goals and
individual accomplishments; and (iii) long-term stock-based incentive awards
designed to strengthen the mutuality of interests between the executive
officers and our stockholders. As an officer's level of responsibility
increases, a greater proportion of his or her total compensation will be
variable and dependent upon our financial performance and stock price
appreciation rather than base salary.

     FACTORS. The principal factors that were taken into account in establishing
each executive officer's compensation package for the 2004 fiscal year are
described below. However, the Compensation Committee may in its discretion apply
entirely different factors, such as different measures of financial performance,
for future fiscal years.

     BASE SALARY. In setting base salaries, the Compensation Committee engaged a
nationally recognized executive compensation consulting firm. The consulting
firm provided compensation data for comparable positions from six nationally
published surveys. The base salary for each officer reflects the salary levels
for comparable positions in the published surveys, as well as the individual's
personal performance. The relative weight given to each factor varies with each
individual in the sole discretion of the Compensation Committee. Each executive
officer's base salary is evaluated periodically on the basis of (i) the
Compensation Committee's evaluation of the officer's personal performance for
the year and (ii) the competitive marketplace for persons in comparable
positions. Our performance and profitability may also be a factor in determining
the base salaries of executive officers.

     VARIABLE PERFORMANCE AWARDS. The variable performance awards have typically
been paid in cash quarterly payments based on the preceding quarterly results.
These payments, when the criteria are satisfied, are paid out shortly after the
release of the quarterly financial results. The cash awards are tied to a blend
of overall company financial performance metrics, individual performance metrics
and company-wide operating profits as a percent of revenue, which may exclude
certain non-cash charges or otherwise be adjusted at the discretion of the
Compensation Committee. The targeted cash awards are based on the published
survey data for each position. Typically, the Compensation Committee reviews the
variable performance targets in conjunction with the fiscal year operating plan
discussions.

     Non-officer employees also participate in the variable cash compensation
plan. Bonuses are typically paid quarterly to eligible individuals according to
a written plan which prescribes a payout percentage of base salary based on the
overall company financial performance. The payout has typically been in the
range of 5 to 1.5% of base salary for most employees.

     LONG TERM INCENTIVES. Generally, stock option grants to executive officers
are made at the discretion of the Compensation Committee. Each grant is designed
to align the interests of the executive officer with those of the stockholders
and to provide each individual with a significant incentive to manage the
company from the perspective of an owner with an equity stake in the business.
Each grant allows the officer to acquire shares of common stock at a fixed price
per share (the market price on the grant date) over a specified period of time
(up to ten years). Each option becomes exercisable in a series of installments
over a multi-year period, contingent upon the officer's continued employment.
Accordingly, the option will provide a return to the executive officer only if
he or she remains employed during the vesting period, and then only if the
market price of the shares appreciates over the option term.

     The size of the option grant to executive officers is set by the
Compensation Committee at a level that is intended to create a meaningful
opportunity for stock ownership based upon the individual's current position,
the individual's personal performance in recent periods and his or her potential
for future responsibility and promotion over the option term. The Compensation
Committee also takes into account the number of unvested options held by the
executive officer in order to maintain an appropriate level of equity incentive
for that individual. The relevant weight given to each of these factors varies
from individual to individual. The Compensation Committee has established
certain guidelines with respect to the option grants made to the executive
officers but has the flexibility to make adjustments to those guidelines at its
discretion.


                                       22


     CEO COMPENSATION. In setting the total compensation payable to the Chief
Executive Officer for the 2004 fiscal year, the Compensation Committee
considered published survey data provided by our compensation consulting firm as
well as the compensation paid to the chief executive officers of seven companies
selected for comparative purposes. The Chief Executive Officer's compensation is
based on the same criteria described above with respect to executive officers
generally. The Chief Executive Officer's variable cash compensation was tied to
the company's revenue and operating profit as a percentage of revenue.

     COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(M). Section 162(m) of the
Internal Revenue Code precludes the company from taking a deduction for
compensation in excess of $1 million for the officers named in the Summary
Compensation Table. Certain performance-based compensation is specifically
excluded from the deduction limit. The company's policy is to qualify, to the
extent reasonable, the compensation of executive officers for deductibility
under applicable tax laws. However, the Compensation Committee believes that
it's primary responsibility is to provide a compensation program that will
attract, retain and reward the executives who will further the Company's success
and that the loss of a tax deduction may be necessary in some circumstances.

     It is the opinion of the Compensation Committee that the executive
compensation policies and plans provide the necessary total remuneration program
to properly align the Company's performance and the interests of the Company's
stockholders through the use of competitive and equitable executive compensation
in a balanced and reasonable manner, for both the short and long-term.

          24, 2000 at our initial public offering price of $31.00 per share and
          in each index at the market close on March 24, 2000, and that all
          dividends were reinvested. No cash dividends have been declared on our
          common stock.

     (3)  Stockholder returns over the indicated period should not be considered
          indicative of future stockholder returns.

NO INCORPORATION BY REFERENCE OF CERTAIN PORTIONS OF THIS PROXY STATEMENT

     Notwithstanding anything to the contrary set forth in any of our previous
filings made under the Securities Act of 1933, as amended, or the Securities
Exchange Act of 1934, as amended, that might incorporate future filings made by
us under those statutes, neither the preceding Stock Performance Graph, the
Audit Committee Report nor the Compensation Committee Report is to be
incorporated by reference into any such prior filings, nor shall such graph or
report be incorporated by reference into any future filings made by us under
those statutes.

      COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

     The members of our Board of Directors, the executive officers and persons
who hold more than 10% of our outstanding common stock are subject to the
reporting requirements of Section 16(a) of the Securities Exchange Act of 1934
which require them to file reports with respect to their ownership of the common
stock and their transactions in such common stock. Based upon (i) the copies of
Section 16(a) reports which we received from such persons for their 2004 fiscal
year transactions in the common stock and their common stock holdings and (ii)
the written representations received from one or more of such persons that no
annual Form 5 reports were required to be filed by them for the 2004 fiscal
year, we believe that all reporting requirements under Section 16(a) for such
fiscal year were met in a timely manner by its directors, executive officers and
greater than ten percent beneficial owners, except that Mr. Coker failed to
timely file a Form 4 with respect to one transaction.


                                  ANNUAL REPORT

     A copy of the annual report for the 2004 fiscal year has been mailed
concurrently with this Proxy Statement to all stockholders entitled to notice of
and to vote at the Annual Meeting. The annual report is not incorporated into
this Proxy Statement and is not considered proxy solicitation material.


                                    FORM 10-K

     We filed an annual report on Form 10-K with the Securities and Exchange
Commission on February 15, 2005. Stockholders may obtain a copy of our annual
report, without charge, by writing to our Corporate Secretary at our principal
executive offices located at 4635 Boston Lane, Austin, Texas 78735.

          and each such registered public accounting firm must report directly

      o  Pre-approve all auditing and permitted non-audit services to be
         performed by the Corporation's auditors.

      o  Obtain, on an annual basis, a formal written statement from the

                                      A-2


                                                                      EXHIBIT B

                            SILICON LABORATORIES INC.

                           CORPORATE GOVERNANCE POLICY

PURPOSE

     The Board of Directors (the "Board") of Silicon Laboratories Inc. (the
"Company") has adopted this Corporate Governance Policy (this "Policy"). This
Policy is subject to requirements of the charters and bylaws of the Company, as
well as applicable law. The Board will review this Policy and other aspects of
the Company's corporate governance as often as it deems necessary and may modify
this Policy or waive any element of this Policy at any time.

ROLE OF DIRECTORS

     The fundamental role of the directors is to exercise their business
judgment to act in what they reasonably believe to be the best interests of the
Company and its stockholders. In fulfilling that responsibility, the directors
may reasonably rely on the honesty and integrity of the Company's senior
management and expert legal, accounting, financial and other advisors.

DIRECTOR QUALIFICATIONS

     Each director should contribute to the experience, skills and other
characteristics required of a properly functioning Board. Criteria include their
personal and professional integrity, depth and breadth of experience, ability to
make independent analytical inquiries, ability to understand the Company's
business, willingness to devote adequate attention and time to duties of the
Board and such other criteria as is deemed relevant by the Nominating and
Corporate Governance Committee. The backgrounds and qualifications of the
directors, considered as a group, should provide a diverse mix of experience,
knowledge and skills.

DIRECTOR INDEPENDENCE

     The Board believes that, as a matter of policy and consistent with
applicable laws, rules and regulations, independent directors should constitute
at least a majority of the Board.

DIRECTOR OUTSIDE ACTIVITIES

     Directors must be willing to devote sufficient time to carry out their
duties and responsibilities effectively, and should be committed to serve on the
Board for an extended period of time. Each Board member is expected to ensure
that other existing and future commitments do not conflict with or materially
interfere with the member's service as a director. Directors are expected to
avoid any action, position or interest that conflicts with an interest of the
Company, or gives the appearance of a conflict.

     A director who also serves as the Company's Chief Executive Officer should
not serve on more than one board of a public company in addition to the Board
and should not serve on the audit committee of any public company. Other
directors should limit their service on the boards of other public companies so
as not to impair the director's service on the Board. All directors should
inform the Chairman of the Nominating and Corporate Governance Committee prior
to joining the board of another public company to ensure that any potential
conflicts, excessive time demands or other issues are carefully considered.

     Directors should offer their resignation to the Board in the event of any
significant change in their personal circumstances, such as a material change in
their principal job responsibilities.

                                      B-1


DIRECTOR NOMINATION PROCESS

     The Nominating and Corporate Governance Committee will review the needs of
the Board for various experience, skills and other characteristics in
determining the director candidates to be nominated at the annual meeting. The
Nominating and Corporate Governance Committee will evaluate candidates for
directors proposed by directors, stockholders or management in light of the
Director Qualification standards. The process for stockholder recommendations
will be determined from time to time by the Nominating and Corporate Governance
Committee and shall be in compliance with the Company's Bylaws and all
applicable laws, rules and regulations. If the Nominating Committee believes
that the Board requires additional candidates for nomination, the Committee will
engage, as appropriate, a third party search firm to assist in identifying
qualified candidates. The nominating process may include interviews and
background and reference checks at the discretion of the Nominating and
Corporate Governance Committee.

RETIREMENT AGE

     The Board believes that 75 is an appropriate retirement age for all
directors.

TERM LIMITS

     The Board does not believe it should establish term limits. While term
limits could help ensure that there are fresh ideas and viewpoints available to
the Board, they hold the disadvantage of losing the contribution of Directors
who have been able to develop, over a period of time, increasing insight into
the Company and its operations and, therefore, provide an increasing
contribution to the Board as a whole.

SIZE OF BOARD

     The Board currently has eight members. The Board reviews from time to time
the appropriate size of the Board. The Board will consider changing its size to
accommodate outstanding candidates or to satisfy specific governance needs.

SEPARATION OF CHAIRMAN AND CHIEF EXECUTIVE OFFICER

     The Board separates the role of Chairman of the Board from the role of
Chief Executive Officer, believing that this currently provides the most
efficient and effective leadership model for the Company.

STOCK OWNERSHIP

     The board believes that directors and officers should generally own stock
in the Company in order to align their interests with the long-term interests of
the Company's stockholders.

EXECUTIVE SESSIONS OF INDEPENDENT DIRECTORS

     The independent directors of the Board will generally meet in executive
session at the end of each regularly scheduled Board meeting and at any other
time requested by a majority of the independent directors.

BOARD ACCESS TO MANAGEMENT

     The independent members of the Board shall have access to Company employees
in order to obtain any information they deem appropriate to fulfill their
duties. The Board may establish a process for such inquiries. Management is
encouraged to invite Company employees to Board meetings where management
participation will provide the Board with additional insight into the matters
being considered.


                                      B-2


RETENTION OF ADVISORS/CONSULTANTS

     The Board and each committee of the Board shall have the authority to
retain outside financial, legal or other advisors as they deem appropriate, and
shall have the authority to obtain advice, reports or opinions from internal and
external counsel and advisors, without consulting with or obtaining approval
from any officer of the Company.

BOARD AND COMMITTEE EVALUATION

     The Board and each committee will perform a periodic self-evaluation. Each
director will be requested to participate in an assessment of the effectiveness
of the Board and any committee on which such director serves. The assessment of
each committee will be reported by the chairman of such committee to the full
Board.

COMMUNICATIONS BY STOCKHOLDERS WITH DIRECTORS

     Stockholders may communicate with any or all Company directors by
transmitting written correspondence addressed to:

                         Board of Directors
                         c/o Corporate Secretary

                         Austin, TX 78735

     Any such communication must contain (i) a representation that the
stockholder is a holder of record of stock of the corporation, (ii) the name and
address, as they appear on the corporation's books, of the stockholder sending
such communication and (iii) the class and number of shares of the corporation
that are beneficially owned by such stockholder. The Corporate Secretary will
forward such communications to the Board or the specified individual director to
whom the communication is directed unless such communication is deemed unduly
hostile, threatening, illegal or similarly inappropriate, in which case the
Corporate Secretary has the authority to discard the communication or to take
appropriate legal action regarding such communication.

ATTENDANCE OF DIRECTORS AT ANNUAL STOCKHOLDER MEETINGS

     The Company will make every effort to schedule its annual meeting of
stockholders at a time and date to maximize attendance by directors. All
directors shall make every reasonable effort to attend the Company's annual
meeting of stockholders.

COMMITTEES

     The Board shall have an Audit Committee, a Compensation Committee, and a
Nominating and Corporate Governance Committee. The Board may from time to time
establish additional committees as necessary or appropriate. Committee members
will be appointed by the Board upon the recommendation of the Nominating and
Corporate Governance Committee. Consideration should be given to rotating
committee members periodically, but rotation should not be mandated as a policy.
Each committee will generally have its own charter. The charters will set forth
the purposes of the committees as well as qualifications for committee
membership.

     The Chairman of each committee, in consultation with the committee members
and senior management, will determine the frequency and length of the committee
meetings consistent with any requirements set forth in the committee's charter.
The Chairman of each committee, in consultation with the appropriate members of
the committee and management, will develop the committee's agenda.

                                      B-3


SUCCESSION PLANNING

     The Board (or a committee thereof) shall conduct a periodic review of the
Company's succession planning, including policies and principles for Chief
Executive Officer selection and succession in the event of an emergency or the
retirement of the Chief Executive Officer. If such review is conducted by a
committee, the committee shall report its recommendation to the Board for
approval.

PROHIBITION ON LOANS

     The Company shall not make any loan to any director or executive officer.
