Conexant Launches Family of Highly Integrated VoIP Solutions for Enterprise and Consumer Phone Applications

Single-Chip, Feature-Rich IP 'Phone-on-a-Chip' Delivers Cost and Performance Benefits

NEWPORT BEACH, Calif.--Sept. 6, 2005--Conexant Systems, Inc. (NASDAQ:CNXT), a worldwide leader in semiconductor solutions for broadband communications, enterprise networks and the digital home, today announced the first in a family of integrated voice over Internet protocol (VoIP) phone solutions. The single-chip CX90600 system solution targets IP- and Web-based desktop phone terminals for business and residential applications. VoIP is a packet-based technology that allows users to make phone calls over the Internet instead of using the standard public switched telephone network. The highly integrated chip reduces bill-of-material (BOM) costs and design complexity, enabling product developers to quickly bring cost-effective and feature-rich VoIP terminals to market.

"The CX90600 is designed to meet the functionality and price point that developers of enterprise and consumer desktop IP telephony products require," said Zeev Collin, vice president of Voice Access Products for Conexant. "Moving forward, we will focus on delivering modular, combination products that leverage our Wi-Fi, video and DSL product portfolios in order to address converged voice, video, broadband access and networking market opportunities."

Industry analyst firm IDC expects the VoIP semiconductor market to grow from $338 million in 2004 to $1.7 billion in 2008. Market drivers include increased VoIP functionality in DSL and cable modem customer premise equipment, and increased demand for IP phones and PBXs.

The flexible architecture of the CX90600 allows manufacturers to use a common design to support a wide range of application options including Web browsing, Wi-Fi billing, and video conferencing. The chip is based on the ARM926EJ core and includes a rich set of peripheral interfaces that enable connectivity to smart cards, flash drives, video cameras and 802.11 a/g wireless LANs. Integrated interfaces include a three-port Ethernet switch to enable local and wide area network connections, a universal serial bus (USB) 2.0 controller, a high-performance peripheral component interconnect (PCI) 2.3 interface, a high-speed universal asynchronous receive/transmitter (UART), a keypad interface, a FXO interface, a FlexIO interface, and several general purpose I/Os.

Advanced voice features support a wide variety of low bit rate and wideband speech coding schemes including G.711, G.722, G.726 and G.729ab, as well as dual-tone multi-frequency (DTMF) and dial tone detection/generation telephony algorithms without the need for an external digital signal processing (DSP) device. The CX90600 also provides acoustic echo cancellation capability for high-quality voice transmissions and full-duplex speakerphone.

In addition, the CX90600 features an integrated memory management unit (MMU), a high-resolution liquid crystal display (LCD) controller, caches, tightly coupled memory (TCM), and an analog codec allowing for a single-chip IP phone design.

Conexant has a long history in voice band processing, and holds an extensive intellectual property portfolio in voice processing and coding technology. The company's field-proven voice technology has enabled more than 100 million voice/data modems, and has been incorporated in millions of voice ports and wireless cellular telephones. The company's VoIP products include voice coprocessors and codecs to enable the easy addition of voice to networked devices, complete system solutions including network processors, and a suite of application software and reference designs.

Availability, Packaging and Pricing

Samples of the CX90600 are available now, with production quantities scheduled for November. The device is packaged in a 324-pin flat pack ball grid array (FPBGA), and priced at $15.00 in quantities of 10,000.
