AUSTIN, Texas – November 20, 2000 – Cirrus Logic, Inc. (NASDAQ:CRUS) today announced it has signed a DVD decoder technology license agreement with LuxSonor Semiconductors, Inc., a leading developer of single-chip A/V decoders for DVD and VCD movie players. The agreement broadens Cirrus Logic’s portfolio to now incorporate DVD decoder integrated circuits alongside its market leadership audio products.

“This technology license allows Cirrus Logic to take advantage of its dominant position in audio chips for consumer electronics providing our customers a single-source solution for both audio and video technology,” said Jason Carlson vice president and general manager, Consumer Products/Data Acquisition Division. “Today, we are the most complete one-stop shop for consumer electronic A/V manufacturers.”

Technologies included in the complete DVD license are MPEG-2 video decoding, video DSP processing, a 32-bit audio DSP, audio and video DSP software, DVD navigation software, and DVD player reference designs. Currently LuxSonor is successfully gaining DVD player market share in China utilizing this technology package.
