  measurements provided in the press release furnished herewith do not replace
  the presentation of Silicon Laboratories&#146; GAAP financial results. These
  additional measurements merely provide supplemental information to assist

  operations; however, these measures are not in accordance with, or an
  alternative to, GAAP and may be different from non-GAAP measures used by other
  companies. Silicon Laboratories has chosen to provide this information to
  investors because it believes that such supplemental information enables them
  to perform meaningful comparisons of past, present and future operating results,
  and as a means to highlight the results of core ongoing operations.</font></p>

  Item 2.02. Results of Operations
  and Financial Condition
  On April 30, 2008,
  Silicon Laboratories Inc. ("Silicon Laboratories") issued a press release
  describing its results of operations for its fiscal quarter ended April 5,
  2008.  A copy of the press release is
  attached as Exhibit 99 to this report.
  Item
  9.01. Financial Statements and Exhibits
  (d) Exhibits.
  99  Press Release of Silicon Laboratories Inc.
  dated April 30, 2008.
  Use of Non-GAAP Financial
  Information
  From time to time,
  Silicon Laboratories provides certain non-GAAP financial measures as additional
  information relating to its operating results.  The non-GAAP financial
  measurements provided in the press release furnished herewith do not replace
  the presentation of Silicon Laboratories' GAAP financial results. These
  additional measurements merely provide supplemental information to assist
  investors in analyzing Silicon Laboratories' financial position and results of
  operations; however, these measures are not in accordance with, or an
  alternative to, GAAP and may be different from non-GAAP measures used by other
  companies. Silicon Laboratories has chosen to provide this information to
  investors because it believes that such supplemental information enables them
  to perform meaningful comparisons of past, present and future operating results,
  and as a means to highlight the results of core ongoing operations.
  Pursuant to the
  requirements of Regulation G, we have provided in the press release furnished
  with this report a reconciliation of the non-GAAP financial measures to the
  most directly comparable GAAP financial measures.
  The information in this
  report, including the exhibit hereto, shall not be deemed to be "filed" for
  purposes of Section 18 of the Securities Exchange Act of 1934, as amended,
  or otherwise subject to the liability of that section.  The information
  contained therein and in the accompanying exhibit shall not be incorporated by
  reference into any filing with the U.S. Securities and Exchange Commission made
  by Silicon Laboratories, whether made before or after the date hereof,
  regardless of any general incorporation language in such filing.
