ITEM 7. FINANCIAL  STATEMENTS, PRO FORMA INFORMATION AND EXHIBITS


(c) Exhibits.


99       Press Release of Silicon Laboratories Inc. dated July 21, 2003 entitled
         "Silicon Laboratories Reports Record Financial Results."  Also see Item
         12 below.


ITEM 12. RESULTS OF OPERATIONS AND FINANCIAL CONDITION


         On July 21, 2003, Silicon Laboratories Inc. issued a press release
describing its results of operations for its fiscal quarter ended June 28, 2003.
A copy of the press release is furnished as Exhibit 99 to this report.

                      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 herein 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.
