Xilinx Press Release #0255

FOR IMMEDIATE RELEASE

SAN JOSE, Calif., and Beaverton, Ore., March 27, 2002 —Xilinx, Inc., (NASDAQ:XLNX) and    Network Elements Inc.(NEI), a leading provider of high speed optical networking modules, today reported the use of Xilinx Virtex-II Platform FPGA technology as an interface and validation for Network Elements’ Lithium 10Gb/s multi-protocol optical networking module; the world’s only 10Gb/s module with integrated multi-protocol processing capabilities.  Network Elements’ Lithium module interfaces to a Xilinx Virtex-II XC2V1000 using SPI-4 protocol on a 17-bit DDR LVDS bus running at an impressive rate of 800 Mb/s. 

“Our validation platform really proved the capabilities of the Virtex-II FPGA,” said Don Husby, design engineer at Network Elements.  “In addition to the IO speeds, a large chunk of the internal logic runs at 400 MHz which is near the theoretical limits of the chip.”   The design also benefited from the abundance of internal DLLs and the use of the Virtex-IISRL to implement large LFSR random number generators.  “The random packet generator used 128 slices, but would have used 16 times the resources in a competitor’s FPGA.”

 “We are pleased to be a vehicle through which Network Elements can bring such world class products to the Networking and Communications market,” said Erich Goetting, vice president and general manager of the advanced product division at Xilinx.
