the shares of Common Stock to be offered hereunder has been passed upon for the
Registrant by DLA Piper US LLP (&#147;DLA&#148;).&nbsp; As of February 22, 2007, certain
attorneys of DLA (directly and indirectly) owned approximately 3,000 shares of
the Common Stock of the Registrant.</p>

<p style="margin:0pt 0pt 12.0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Section 145 of the
Delaware General Corporation Law (the &#147;DGCL&#148;) 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&#160; (including attorneys&#146; fees)
incurred by him as a result of such action, 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>

<p style="margin:0pt 0pt 12.0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Registrant&#146;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.&#160; The Registrant&#146;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&#146;
and officers&#146; liability insurance.</font></p>

<p style="margin:0pt 0pt 12.0pt;text-indent:0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In the event that a claim for 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.</font></p>

PART II
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 30, 2006, filed with the Commission on February 7,
2007.
(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
Legal Opinion
.  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 22, 2007, 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

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.
II-2
In the event that a claim for 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 ­­­­22
nd
day of February, 2007.
