Business Editors/High-Tech Writers

China Cable Broadcasting Network Exhibition

BEIJING--(BUSINESS WIRE)--March 15, 2004

WHO:      Conexant Systems, Inc. (NASDAQ:CNXT), the worldwide leader
          in semiconductor solutions for broadband communications,
          enterprise networks and the digital home, will be
          demonstrating several new semiconductor system platforms for
          interactive and basic cable, satellite, and IP set-top box
          (STB) products during the China Cable Broadcasting Network
          Exhibition (CCBN 2004).

          Product demonstrations will be held March 23-25 at the
          Radisson SAS Hotel, next to the exhibition center in
          Beijing.

ATTN:     Editors and industry analysts covering DTV and STB products
          and technologies.

WHAT:     Conexant will demonstrate several new STB reference design
          platforms based on its DVB-C, DVB-S, PVR and IP
          technologies.

          The DVB-C STB reference design is a compact, cost-effective
          and is based on Conexant's CX24147 TV decoder IC. The
          CX24147 has an integrated VCXO, complete system clock
          generation from a single crystal, and high quality 10-bit
          video DACs. The low cost front-panel design enables
          manufacturers to reduce the BOM cost for STBs.

          The DVB-S satellite STB reference design is based on
          Conexant's CX24142 single chip DBS TV decoder IC. In
          addition to the features of the CX24147 device, the CX24142
          includes an integrated QPSK demodulator and FEC decoder,
          DiSEqC 2.x support for two-way communication between STB and
          LNB, and a direct interface to the Conexant front-end
          silicon tuner CX24109. The result is a high-performance,
          low-cost STB design useful for worldwide DVB-S markets.

          The PVR interactive cable STB platform, based on Conexant's
          CX24430 device, enables a DOCSIS/EuroDOCSIS 1.0/1.1 and
          DVB-compliant broadband interactive channel with integrated
          cable modem and advanced PVR support for simultaneous
          recording and viewing of two channels. A powerful 250 MHz
          ARM920T CPU supports STB applications, including advanced
          cable STB platforms that can be developed rapidly using this
          reference design platform.

          The IP STB platform is based on Conexant technology that
          decodes DSL-delivered, IP-based MPEG content for display on
          a television. Formats supported include MPEG-1/2/4, H.264,
          AVC and WMV. Home networking, with all wired and wireless
          technologies, is also supported.
