Single FPGA Solution for 100-Gigabit Ethernet


Xilinx announced a single-FPGA solution for telecommunications equipment manufacturers developing 40- and 100-Gigabit Ethernet (GE) solutions. Xilinx has added the Virtex-5 TXT platform to its family of 65-nanometer FPGAs. The platform consists of two devices that deliver 6.5Gbps serial transceivers, and are fully supported with application-specific IP, development tools, and reference designs for implementing high-bandwidth protocol bridging. According to Communications Industry Researchers (CIR) analyst Lawrence Gasman, the industry efforts led by the IEEE to create 40- and 100-GE systems will result in $4.3 billion in annual revenues by 2016.

 Flexible FPGA Architecture The ASMBL architecture first introduced with Virtex-4 FPGA family enables Xilinx to develop and deploy domain-optimized silicon platforms targeted at the technical requirements of specific markets and applications. With its 48 6.5Gbps GTX transceivers, the Virtex-5 TXT platform is optimized for 100GE applications. It is designed to improve signal integrity for reliable operation of 10/100Gbps links, lower power consumption per channel for better reliability, and provide programmable support for multiple protocols, thus easily adapted to evolving standards for the interface between 100Gbps optical modules and the media access controller (MAC). Virtex-5 TXT devices offer a single-chip solution with built-in flexibility and re-programmability to scale as 40GE and 100GE hardware requirements and standards mature, while delivering the 600Gbps total bandwidth required today to build network bridges such as:

    100GbE to 120Gbps Interlaken
     40Gbps Quad XAUI to 50Gbps Interlaken
     OC-768 to OTU-3
     SFI-5 to 4xSFI4.2

 Perfomance

The bandwidth capabilities of the Virtex-5 TXT platform are also well suited for high-performance computing and video broadcast applications. In November of 2006, Xilinx FPGAs were used to showcase the world's first successful 100GE transmission through a live production network demonstrated at SC06 International Conference by Finisar, Level3 Communications, Internet2, and the University of California at Santa Cruz (UCSC). In June of this year, telecommunications services giant Comcast Corporation announced the successful completion of a 100GE technology test over its existing backbone infrastructure between Philadelphia and McLean, VA using the industry's first 100GE router interface. The system used Sarance Technologies' High Speed Ethernet IP Core (HSEC) running on a Virtex-5 FXT FPGA, which is now available as part of the new Virtex-5 TXT solution.
Pricing and Availability

Customers can begin designing with Virtex-5 TXT FPGA devices using the ISE design suite service pack 3 available online. The HSEC IP core is available from Sarance Technologies. The Virtex-5 TX150T and Virtex-5 TX240T devices will begin sampling by the end of calendar 2008 with production devices available in the first quarter of 2009. The TX150T device will list for under US$500 in 5,000 unit volumes by second half of 2009. The Virtex-5 EasyPath program supports Virtex-5 TXT devices for high-volume cost reductions.
