Xilinx breaks the 2 Tbps bandwidth barrier with transceiver-packed Virtex-7 X690T FPGAs

March 30, 2012 // By Julien Happich
Xilinx announced the first shipments of its Virtex-7 X690T FPGA, combining what the company claims to be the industry's most reliable high-speed serial transceivers, highest system bandwidth, and market-optimized FPGA resources.

The Virtex-7 X690T FPGA is the first of a set of devices in the 7 series to address advanced high-performance wired communication applications that require low power, single-chip solutions. These devices enable fast, scalable and easy-to-implement chip-to-chip serial interfaces, robust 10GBASE-KR backplanes that maximize bandwidth while supporting the various board-to-board distances of next-generation communication systems, and high signal-integrity interfaces to the latest optical modules validated to support cable distances of up to 80km. Customers who need even greater system capacity and bandwidth can easily migrate to the Virtex-7 X1140T FPGA, built using 3D Stacked Silicon Interconnect technology on the 7 series FPGA scalable optimized architecture. Shipments of footprint-compatible Virtex-7 X1140T FPGAs with 96 GTH transceivers will follow in May.

The FPGAs can be used to implement advanced packet processing, FEC, quality-of-service, switching, and traffic management algorithms as well as next generation EdgeQAM. Engineers can the dynamically controllable GTH serial transceivers, including fully programmable three-tap FIRs that enable the transmitter de-emphasis needed to deal with the widest range of environments, along with fully-adapting seven fixed and four sliding tap receiver decision feedback equalization (DFE) circuits. To accelerate design and debugging, each GTH transceiver also includes a non-destructive, high-resolution 2D eye scan circuit that allows designers to see and measure the receiver eye from within the FPGA. With 80 GTH transceivers that run up to 13.1 Gbps, the Virtex-7 X690T FPGA is first FPGA to break the 2 Tbps single FPGA device bandwidth barrier. By leveraging the advanced 7 series FPGA architecture built on the TSMC 28HPL process, customers can save greater than 25 percent total power over competing similar-density FPGAs, allowing them to achieve the integration they need to build next-generation systems that achieve performance and low power requirements. Virtex-7 X690T FPGA engineering samples are available today.
