against, in the case of a non-derivative action, judgments, fines, amounts paid
in settlement and reasonable expenses&#160;

and in the case of a derivative action, against expenses (including attorneys&#146;
fees), if in either type of action he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Registrant. This indemnification does not apply, in a derivative action, to
matters as to which it is adjudged that the director, officer, employee or
agent is liable to the Registrant, unless upon court order it is determined
that, despite such adjudication of liability, but in view of all the
circumstances of the case, he is fairly and reasonably entitled to indemnity
for expenses, and, in a non-derivative action, to any criminal proceeding in
which such person had no reasonable cause to believe his conduct was unlawful.</font></p>

to indemnify its directors and executive officers to the fullest extent

Information Required in the
Registration Statement
Item 3.
Incorporation of Documents by Reference
Silicon Laboratories Inc. (the "Registrant") hereby
incorporates by reference into this Registration Statement the following
documents previously filed with the Securities and Exchange Commission (the "Commission"):
(a)
The Registrant's latest Annual Report on Form 10-K
containing audited financial statements for the fiscal year ended December 29,
2007, filed with the Commission on February 7, 2008.
(b)
All other reports filed pursuant to Section 13(a) or
15(d) of the Securities Exchange Act of 1934, as amended (the "1934 Act")
since the end of the fiscal year covered by the Registrant's Annual Report
referred to in (a) above; and
(c)
The Registrant's Registration Statement No. 000-29823
on Form 8-A filed with the Commission on March 7, 2000 pursuant to Section 12
of the 1934 Act, in which there is described the terms, rights and provisions
applicable to the Registrant's outstanding Common Stock.
All reports and definitive proxy or information
statements filed pursuant to Section 13(a), 13(c), 14 or 15(d) of the
1934 Act after the date of this Registration Statement and prior to the filing
of a post-effective amendment which indicates that all securities offered
hereby have been sold or which de-registers all securities then remaining
unsold shall be deemed to be incorporated by reference into this Registration
Statement and to be a part hereof from the date of filing of such documents.
Item 4.
Description of Securities
The class of securities to be offered is registered
under Section 12 of the 1934 Act.
Item 5.
Interests of Named Experts and Counsel
The validity of the shares of Common Stock to be
offered hereunder has been passed upon for the Registrant by DLA Piper US LLP ("DLA"). 
As of February 7, 2008, certain attorneys of DLA (directly and indirectly)
owned approximately 3,000 shares of the Common Stock of the Registrant.
Item 6.
Indemnification of Directors and Officers
Section 145 of the Delaware General Corporation Law (the "DGCL")
provides, in effect, that any person made a party to any action by reason of
the fact that he is or was a director, officer, employee or agent of the
Registrant may and, in some cases, must be indemnified by the Registrant
against, in the case of a non-derivative action, judgments, fines, amounts paid
in settlement and reasonable expenses 
(including attorneys' fees) incurred by him as a result of such action,
and in the case of a derivative action, against expenses (including attorneys'
fees), if in either type of action he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Registrant. This indemnification does not apply, in a derivative action, to
matters as to which it is adjudged that the director, officer, employee or
agent is liable to the Registrant, unless upon court order it is determined
that, despite such adjudication of liability, but in view of all the
circumstances of the case, he is fairly and reasonably entitled to indemnity
for expenses, and, in a non-derivative action, to any criminal proceeding in
which such person had no reasonable cause to believe his conduct was unlawful.
The Registrant's certificate of incorporation provides that no director
shall be liable to the Registrant or its stockholders for monetary damages for
breach of fiduciary duty as a director to the fullest extent permitted by the
DGCL.  The Registrant's bylaws require it
to indemnify its directors and executive officers to the fullest extent
permitted by Delaware law. The Registrant has entered into indemnification
agreements with all of its directors and executive officers and has purchased
directors' and officers' liability insurance.
II-1
Reference is made to the underwriting agreement filed as Exhibit 1.1
to Registrant's Registration Statement No. 333-94853, pursuant to which
the underwriters have agreed to indemnify the Registrant's officers and
directors against certain liabilities under the Securities Act.

Item 9.
Undertakings
.
A.            The
undersigned Registrant hereby undertakes: 
(1) to file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement (i) to
include any prospectus required by Section 10(a)(3) of the Securities
Act of 1933 Act, as amended (the "1933 Act"), (ii) to reflect in the
prospectus any facts or events arising after the effective date of this
Registration Statement (or the most recent post-effective amendment thereof)
which, individually or in the aggregate, represent a fundamental change in the
information set forth in this Registration Statement and (iii) to include
any material information with respect to the plan of distribution not
previously disclosed in this Registration Statement or any material change to
such information in this Registration Statement; provided, however, that
clauses (1)(i) and (1)(ii) shall not apply if the information
required to be included in a post-effective amendment by those clauses is
contained in periodic reports filed with or furnished to the Commission by the
Registrant pursuant to Section 13 or Section 15(d) of the 1934
Act that are incorporated by reference into this Registration Statement; (2) that
for the purpose of determining any liability under the 1933 Act each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof; and (3) to
remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the
Registrant's 2000 Stock Incentive Plan, as amended and restated March 8,
2001, and Employee Stock Purchase Plan.
B.            The
undersigned Registrant hereby undertakes that, for purposes of determining any
liability under the 1933 Act, each filing of the Registrant's annual report
pursuant to Section 13(a) or Section 15(d) of the 1934 Act
that is incorporated by reference into this Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
C.            Insofar
as indemnification for liabilities arising under the 1933 Act may be permitted
to directors, officers, or controlling persons of the Registrant pursuant to
the indemnification provisions summarized in Item 6 or otherwise, the
Registrant has been advised that, in the opinion of the Commission, such
indemnification is against public policy as expressed in the 1933 Act, and is,
therefore, unenforceable.  In the event
that a claim for
II-2
indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer, or controlling person of the Registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer, or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the 1933 Act and will be governed by the
final adjudication of such issue.
II-3
SIGNATURES
Pursuant to the requirements of the Securities Act of
1933, as amended, the Registrant certifies that it has reasonable grounds to
believe that it meets all of the requirements for filing on Form S-8, and
has duly caused this Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the City of Austin, State of Texas
on this 5th day of February, 2008.
