<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On November 8, 2006,
Silicon Laboratories Inc. (&#147;Silicon Laboratories&#148;) issued a press release
announcing the appointment of William Bock as senior vice president of finance
and administration and chief financial officer, effective as of November 8,
2006.&#160; Mr. Bock served as a director on
Silicon Laboratories&#146; board since the company went public in March 2000 and
resigned from the board effective as of November 8, 2006.&#160; From April 2002 until November 2006,
Mr.&nbsp;Bock was a partner with CenterPoint Ventures, a venture capital firm.
From April&nbsp;2001 to March&nbsp;2002, Mr.&nbsp;Bock served as a partner of
Verity Ventures, a venture capital firm.&#160;
From June&nbsp;1999 to March&nbsp;2001, Mr.&nbsp;Bock served as a vice

chief executive officer of DAZEL Corporation, a provider of electronic

October&nbsp;1994 to February&nbsp;1997, Mr. Bock served as executive vice
president and chief operating officer of Tivoli Systems, a client server

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Mr. Bock replaces Paul

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The press release
announcing the appointment of Mr.&nbsp;Bock is attached hereto as
Exhibit&nbsp;99.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Silicon
Laboratories entered into an employment agreement (the &#147;Employment Agreement&#148;)
with Mr. Bock in connection with his appointment.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Under
the Employment Agreement, Mr. Bock will receive an annual base salary of
$300,000. &nbsp;The Employment Agreement also provides that Mr. Bock will be
eligible to participate in Silicon Laboratories&#146; 2007 Bonus Plan, with an
annual target payout of $300,000. &nbsp;Upon his commencement of services on
November 8, 2006 (the &#147;Start Date&#148;), Mr. Bock will receive a nonstatutory stock
option to purchase 250,000 shares of Silicon Laboratories Common Stock under
the 2000 Stock Incentive Plan, with an exercise price per share equal to the

Date.&nbsp; The options will be subject to a five-year vesting schedule.
&nbsp;In addition, Mr. Bock will receive an award of 75,000 restricted stock
units under the 2000 Stock Incentive Plan which will vest in five annual
installments on each anniversary of the Start Date.&nbsp; In the event of Mr.
Bock&#146;s Involuntary Termination for reasons other than Misconduct (as such terms
are defined in the Employment Agreement), Mr. Bock would be entitled to
severance equal to his annual salary and bonus following his execution of a
full general release of claims against Silicon Laboratories.&nbsp; If such
Involuntary Termination for reasons other than Misconduct were to occur
following a Change in Control (as defined in the 2000 Stock Incentive Plan),
Mr. Bock would become fully vested with respect to the options and restricted
stock units.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
foregoing description is subject to, and qualified in its entirety by, the

Texas, Nov. 8, 2006 &#151; </font></b>Silicon
Laboratories Inc. (Nasdaq: SLAB), a leader in high- performance,
analog-intensive, mixed-signal ICs, today announced the appointment of William
Bock as senior vice president of finance and administration and chief financial
officer, effective immediately.</p>

<p style="color:windowtext;margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Mr. Bock will be
resigning as a director on Silicon Laboratories&#146; board where he served as
chairman of the audit committee since the company went public in March,
2000.&#160; In addition to his familiarity
with Silicon Laboratories&#146; products, strategy and mixed-signal history, Mr.
Bock brings to the company thirty years of business acumen spanning finance,
operations and sales.</font></p>

<p style="color:windowtext;margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&#147;Bill has been closely
engaged with the company&#146;s management team during his tenure on our board,
which will enable him to get up to speed quickly in his new role,&#148; said Necip
Sayiner, president and CEO of Silicon Laboratories. &#147;Bill brings a wealth of
experience from various senior management positions that will be instrumental
in helping the company navigate the next decade of growth and diversification. He
will be a tremendous asset to the company, and I am looking forward to working
closely with him to execute on our business strategy and achieve our financial
goals.&#148;</font></p>

<p style="color:windowtext;margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Prior to joining
Silicon Laboratories, Mr. Bock was a partner at venture capital firms

statements reflect the current views and assumptions of Silicon Laboratories
and are subject to various risks and uncertainties that could cause actual
results to differ materially from expectations. Among the factors that could
cause actual results to differ materially from those in the forward-looking
statements are the following: risks that Silicon Laboratories may not be able
to maintain its historical growth; quarterly fluctuations in revenues and
operating results; volatile stock price; average selling prices of products may
decrease significantly and rapidly, especially for mobile handset products;
dependence on a limited number of products and customers; risks associated with
shifting market demand from GSM/GPRS to EDGE and WCDMA; difficulties developing
new products that achieve market acceptance; risks that Silicon Laboratories
may not be able to manage strains associated with its growth; dependence on key
personnel; difficulties managing our manufacturers and subcontractors;
difficulties managing international activities; credit risks associated with
our accounts receivable; geographic concentration of manufacturers, assemblers,
test service providers and customers in the Pacific Rim that subjects Silicon
Laboratories&#146; business and results of operations to risks of natural disasters,
epidemics, war and political unrest; product development risks;
inventory-related risks; intellectual property litigation risks; risks
associated with acquisitions; the competitive and cyclical nature of the
semiconductor industry and other factors that are detailed in Silicon
Laboratories&#146; filings with the SEC. Silicon Laboratories disclaims any
intention or obligation to update or revise any forward-looking statements,
whether as a result of new information, future events or otherwise.</font></p>
