FOR IMMEDIATE RELEASE

XILINX SHIPS INTERFACE SOLUTIONS FOR FPGA INDUSTRY'S FIRST 10GBPS PHYSICAL LAYER TRANSCEIVER FAMILY

XSBI and SFI-4 interface reference designs used with Xilinx Virtex-II Pro FPGAs and RocketPHY family accelerate adoption of 10Gbps technology

SAN JOSE, Calif., May 6, 2003 - Xilinx, Inc. (NASDAQ: XLNX), today announced the immediate availability of the 644MHz SFI (SerDes Framer Interface)-4 Single Data Rate (SDR) Low Voltage Signaling (LVDS) solution and XSBI (10 Gigabit Sixteen Bit Interface) interfaces optimized for use in the Virtex®-II or Virtex-II Pro™ FPGAs together with Xilinx® RocketPHY™ 10Gbps physical layer transceiver family. These ready-to-use solutions enable system designers of 10 Gigabit Ethernet, OC-192 SONET/SDH and 10Gbps Fibre Channel applications to seamlessly interface between the Xilinx Virtex-II Pro FPGA family and the RocketPHY devices. Xilinx has already demonstrated proven interoperability of the SFI-4 and XSBI interfaces with a wide range of ASSP devices in addition to Xilinx Virtex-II Pro and RocketPHY devices. For complete information regarding the interfaces and Xilinx RocketPHY solutions, visit www.xilinx.com/rocketphy.

"With the introduction of the new RocketPHY devices in conjunction with Xilinx's intellectual property cores and reference designs, Xilinx extends programmable logic into a wide range of new 10 Gbps markets and applications," said Robert Bielby, senior director of Strategic Solutions Marketing at Xilinx. "Through this potent combination of solutions, a wide range of customers and markets will be able to realize the direct benefits of lower cost and higher bandwidth through serial technologies."

About Xilinx SelectLVDS Reference Designs
The 644 MHz SDR SelectLVDS reference design (http://www.xilinx.com/xapp/xapp622.pdf) provides system designers with a ready-to-use solution for the SFI-4 interface to seamlessly interface to the external OC-192 SONET framer and optic modules at 622Mbps. Additionally, the reference design supports both 622Mbps and 644Mbps data rates for direct SFI-4 and XSBI interfacing to the respective external 10Gbps SONET and Ethernet devices. Xilinx is the first company to provide a complete checklist to ensure the reference design is compatible with the OIF SFI4-0.10 specification and the IEEE 802.3ae-2002 specification as part of the detailed application note.

Xilinx also offers a fully scalable and flexible 840Mbps Double Data Rate (DDR) SelectLVDS reference design (http://www.xilinx.com/xapp/xapp265.pdf), allowing designers to implement the 16-bit LVDS channel in any location. The reference design is ideally suited for data traffic aggregation applications. To help designers implement applications such as high speed interfacing between a network processor unit (NPU) and a traffic manager, up to 7 groups of 16-bit transmitter/receiver blocks can be instantiated into a single Virtex-II Platform FPGA. The 840 Mbps reference design also provides multiple-channel options (4b, 16b or 20b) and is optimized for the Virtex-II Platform FPGA.

License Price and Availability
Both reference designs are available now and are downloadable free of charge from Xilinx.com as part of the complete Xilinx Platform FPGA connectivity solutions. Xilinx connectivity solutions address a wide variety of system interconnectivity standards including related IP cores, design services and reference designs from both Xilinx and third-party providers.
