Cypress to mix programmable logic, high-speed serial I/O in new chip series

SAN JOSE -- Cypress Semiconductor Corp. here today announced plans to offer a new series of devices that mix programmable logic and serial interface functions for high-bandwidth communications applications. Cypress said its new family of programmable serial interface chips, called PSI, will reduce system development, complexity and cost.

According to Cypress, the PSI devices will mix programmable logic with a serializer/deserializer (SERDES) function, a high-speed serial interface, communications memory, logic and phase-locked loops (PLLs). The San Jose chip company also said its Warp software will enable a seamless programming interface for integration of custom intellectual property (IP) with the SERDES.

The first members in the new PSI series will become available in 2001, and these devices will enable customers to "integrate their logic IP with our communications devices," said Geoff Charubin, director of marketing at Cypress.

The company said the PSI chips will provide a programmable interface to a SERDES that's compatible with various physical layer transmission media, such as fiber optic modules, copper cables and circuit board traces. Cypress managers said the combined serial bandwidth of 200 megabits per second to 12 gigabits per second will allow PSI devices to meet the requirements of a broad range of market segments, including Gigabit Ethernet, InfiniBand, Fibre Channel, and SONET. The devices will be housed in ball-grid array (BGA) packages.

"Communications backplanes traditionally employ parallel buses; however, designers aiming to meet the demand for bandwidth in networking systems have encountered the speed, noise and scalability limitations of this bus architecture," said Richard Kapusta, senior product marketing manager at Cypress. "Serial connections, on the other hand, eliminate cross-talk while increasing system speed, reducing noise and providing scalability. Serial connections also enable high-speed box-to-box communication. In addition, system reliability and serviceability are greatly enhanced."
