Altera Releases SerialLite II Protocol Optimized for Stratix II GX FPGAs

Second-Generation Serial Protocol Extends Flexibility, Increases Performance and Offers Substantial Cost Savings

SAN JOSE, Calif., Nov. 14 /PRNewswire-FirstCall/ -- Altera Corporation (NASDAQ: ALTR) today announced the release of SerialLite II, a lightweight serial interconnect protocol for chip-to-chip, board-to-board and backplane applications. Optimized for the Stratix(R) II GX device family, the SerialLite II protocol builds on the success of the first-generation SerialLite protocol by supporting a performance range of 622 Mbps to 6.375 Gbps while reducing logic requirements by an average of 65 percent. SerialLite II delivers a low-cost serial interconnect solution for a wide array of applications, including voice, data and video communication, test and medical, defense, industrial, high-end computing and data storage.

"We worked very closely with our original SerialLite customers to define and develop this second-generation serial protocol," said Justin Cowling, Altera's director of IP marketing. "By understanding the unique requirements of different applications over a widening range of performance points, we were able to define a low-latency, low-overhead protocol with a wider set of configurable features to drive down implementation costs for each customer."

About SerialLite II

SerialLite II is a point-to-point serial interconnect protocol based on industry-standard 8b/10b encoding, scalable from 1 to 16 lanes at 622 Mbps to 6.375 Gbps per lane, for chip-to-chip, board-to-board and backplane applications. The protocol includes a flexible architecture to support full-duplex (symmetric), simplex, asymmetric and broadcast operation, and support for either streaming or packet data.
