CAUTIONARY LANGUAGE

        This press release may contain forward-looking statements based on
Silicon Laboratories' current expectations.  These forward-looking statements
involve risks and uncertainties.  A number of important factors could cause
actual results to differ materially from those in the forward-looking
statements. These factors include the widespread market acceptance of DAA

and the integration of Krypton's business, products and technologies into
Silicon Laboratories' business, marketing activities and strategic focus.

financial results and cause actual results to differ materially from those in
the forward-looking statements, please refer to Silicon Labs' recent filings
