Up to four, front-panel, data-port connectors deliver output data at rates up to 320 MB/s. In addition, a VXS interface provides two, 1.25 GB/s, switched, serial-fabric ports to the VME backplane.

Intended for high-performance DSP tasks such as radar, signal intelligence and high-frequency data acquisition, the processing board couples its high-speed A/Ds to two Xilinx Virtex-II Pro FPGAs—each supported by 16 MBs of Flash and 128 MBs of SDRAM. The SDRAM can be used as a circular buffer digital delay or as real-time transient capture memory.

Each FPGA provides the equivalent of six million system gates, enabling users to perform high-frequency signal processing tasks—such as demodulation, convolution, filtering and data analysis. In many applications this reduces the data rate of off-board traffic. Other applications can take advantage of high-speed I/O at the front panel and backplane.

The initial release of the Model 6822 supports Serial RapidIO (VITA 41.2) and the Xilinx Aurora link layer protocols over the VXS port. But there are plans to extend support to include PCI-Express.

The board is available in commercial, air-cooled, and conduction-cooled versions. Pricing of the model 6822 dual-channel A/D VME board with Virtex-II Pro FPGAs and VXS I/O begins at $8,995. Delivery is 12 weeks after receipt of order.
