Conexant Adds Industry's Highest-Speed Crosspoint Switch to Growing Fiber-Optic Networking Family.

NEWPORT BEACH, Calif.--(BUSINESS WIRE)--Oct. 11, 1999--

High-speed, single-chip switch is first to provide easy upgrade

path from 2.5 Gigabits-per-second (Gbps) (OC-48) to 10 Gbps

(OC-192) networks for Internet infrastructure

Conexant Systems Inc. (Nasdaq:CNXT) Monday expanded its offering for the fast-growing digital fiber-optic crosspoint-switching market with a high speed, single-chip solution that is the first to support today's 2.5 Gbps OC-48 networks while providing an easy upgrade path to tomorrow's 10 Gbps OC-192 performance requirements.

Conexant's CXS1610 solution is a differential high-isolation crosspoint switch that is the industry's first to support up to 12.5 Gbps data rates. It uses a cost-efficient 16-port-by-16-port (16x16) matrix density and has the capacity for up to 200 Gbps data throughput. Equipment manufacturers who use the CXS1610 to build fiber-optic communication systems for today's OC-48 networks will have the ability to quickly migrate their equipment to tomorrow's OC-192 performance levels without requiring any new electronic crosspoint-switching integrated circuits.

"The 16x16 CXS1610 joins our recently announced 68x68 solution to create a rapidly growing set of options for manufacturers of large crosspoint switches," said Achim Hill, business director for Conexant's Network Access Division. "Our 68x68 crosspoint switch is the most cost effective, lowest power, highest-density solution for OC-48 network equipment, while our new CXS1610 16x16 switch is the first of its kind to meet both current OC-48 performance requirements and emerging 10 Gbps OC-192 requirements."

Conexant's CXS1610 uses a high-isolation design that adds only 2.5 picoseconds (ps) of single-channel Root Mean Square (RMS) "jitter," which is a critical gauge of how much short-term phase variation a signal experiences because of crosstalk in the circuit. The CXS1610 also features non-blocking switching with a broadcast/multicast capability, and includes both differential and single-ended high-speed inputs and outputs. The inputs are programmed with either 3.3V low voltage Complementary Metal Semiconductor Oxide (CMOS) or Emitted Couple Logic (ECL) levels for added flexibility.

"Conexant is rapidly filling in the full range of end-to-end transmission solutions in the fiber-optic backbone of today's high-speed, multi-service communications networks. Our goal is to build the industry's broadest line of solutions including transceivers, front-end pre-amps, clock-and-data-recovery circuits, laser drivers, and multiplexers and demultiplexers," said Hill.

The CXS1610 is packaged in a 132-pin ceramic quad flatpack (CQFP). The device is manufactured using Conexant's Gallium Arsenide (GaAs) Heterojunction Bipolar (HBT) process technology, one of several small-geometry, high-volume options.

The digital crosspoint-switching matrix is the most common architecture for handling terabits of Internet traffic and other high-volume communications requirements. The majority of today's 44.7 megabit-per-second (Mbps) T3 networks are now being upgraded to 2.4 Gbps OC-48 networks. During the coming months, it is expected that a growing percentage of these 2.5 Gbps OC-48 networks will be upgraded to 10 Gbps OC-192 rates to meet accelerating bandwidth demand for Internet usage and other voice and data communications services. Conexant's growing family of crosspoint switches and other fiber-optic IC components provides key enabling technology for making that important transition.

The CXS1610 switch is priced at $1,790.00 per unit in OEM volumes of 100. It will begin sampling in October and is scheduled to enter volume production in the first quarter of 2000.
