National Semi Intros SerDes

SANTA CLARA, Calif. -- Leveraging its leadership position in the high-speed interface market, National Semiconductor Corporation (NYSE: NSM) today entered the multi-Gigabit serializer/deserializer (SerDes) market with the introduction of a best-in-class 2.5 Gigabit per second (Gbps) transceiver optimized for backplane, cable and fiber optical applications. National's new four-channel SerDes solution enables communications equipment vendors to quadruple the capacity of their existing platforms, preserving the investments of service providers and corporate customers.National's DS25C400 is a four-channel SerDes especially designed to provide a highly robust and reliable 2.5 Gbps per channel solution for backplane interconnect between line cards and switch cards in routers, switches, cross connects and multiplexers. It is ideal for existing FR4 backplanes designed for lower speeds, enabling huge cost savings and "as needed" capacity upgrades.The Internet and communication infrastructure market has undergone tremendous changes recently with an emphasis on system costs and upgrade capabilities. "In today's market, many service providers and corporations prefer to add bandwidth by upgrading existing equipment rather than investing in a completely new platform," said Dave Lewis, Network Interface Business Unit product marketing manager, National Semiconductor. "National's DS25C400, with low output jitter, high jitter tolerance, and pre-emphasis plus equalization allows equipment makers to put 2.5 Gbps through existing backplanes originally designed for lower speeds such as 622 megabit per second (Mbps), quadrupling bandwidth capacity without a chassis redesign. Now equipment vendors can offer their customers increased bandwidth by providing faster add-in cards instead of forcing customers to tear out their old system and buy an entirely new one."National Semiconductor Corp.
