PMC-Sierra and Vativ to Create Interoperable DS3 Line Card Solution

4/27/2004 - PMC-Sierra, Inc. (Nasdaq:PMCS - News) and Vativ Technologies announced a marketing collaboration to deliver interoperable framer/mapper and line interface unit (LIU) devices for next-generation voice and data communications. The high density, multi-channel DS3 equipment line card solution is the industry's lowest power and highest performance framer/mapper and LIU solution currently available. The combination of PMC-Sierra's ARROW, SUNI® and TEMUX® framer/mapper product families and Vativ Technologies' VTE3 DS3 LIUs offer equipment makers a reliable solution to seamlessly upgrade existing infrastructures. A reference design is available that addresses metro transport, access and core markets applications.

"We are pleased to combine Vativ's best-of-breed multi-channel DS3 LIU solution with PMC-Sierra's broad range of integrated framer/mapper products to deliver the industry's lowest power and highest performance multi-channel LIU and framer solution for DS3 applications," said Sreen Raghavan, president and CEO at Vativ Technologies. "The combined solution dissipates less than 3.5W; half the power of competing solutions while delivering unparalleled performance. Vativ's LIU consumes just 75mW per channel in full-duplex operation which enables high port density designs without substantially increasing system power budgets."

"PMC-Sierra and Vativ Technologies' collaboration on the reference design offers our customers with the most optimized DS3 line card solution to address the Metro Transport, Router, and Multi-Service Switch markets," said Jean Lamarche, director of Marketing and Applications, Service Provider Division at PMC-Sierra. "OEMs upgrading existing or developing next-generation line cards have a complete, flexible, and reliable solution set with multi-rate, multi-mode devices that provide significant power and real estate savings."

PMC-Sierra's Portfolio of Framer/Mapper Products
PMC-Sierra provides a wide array of low power, highly integrated framer/mapper devices targeted at DS3/E3/STS-1 applications including metro transport, access and core markets as well as multi-service switching and routing.

Vativ Technologies' Advanced DSP-based Devices
Vativ Technologies' VTE3 DS3/E3/STS-1E LIUs achieve dramatic performance improvements over current "legacy" LIUs due to incorporation of proprietary DSP-based transceiver architecture. For example, the digital adaptive equalizer in the receiver enables the VTE3 device to recover DS3 signals over 3000 feet of coaxial cable (Type 734/738), exceeding the standards requirement by over 3 times. Additionally, the device includes programmability of the transmit pulse shape which results in added flexibility and robustness for system designers.

The VTE3-x LIUs provide customer with:
