The Model 78720 is a multichannel high-speed data converter PCIe board suitable
for connection to HF or IF ports of communications, radar, telemetry, and medical systems. This new board is a member of the Pentek Onyx™ family of products that employ the new Xilinx Virtex-7 FPGAs. The Virtex-7 family delivers the industry's most advanced FPGA technology.

The Pentek 78720 analog front end features three 200 MHz, 16-bit A/Ds delivering excellent dynamic range and 350 MHz input bandwidth, ideal for signal intelligence, radar, beamforming and undersampling applications. In addition, a dual channel 800 MHz 16-bit D/A provides two wideband analog outputs. Built-in interpolation filters and a digital upconverter translate real or complex baseband input signals to any IF center frequency up to 360 MHz.

The Virtex-7 FPGA can be selected from the VXT family to match the specific requirements of the processing task. Supported FPGAs include: VX330T, VX485T or VX690T. The VX690T features up to 3600 DSP48E1 slices and is ideal for tasks such as modulation/demodulation, encoding/decoding, encryption/decryption, or channelization of the signals between transmission and reception. For applications not requiring large DSP resources, one of the lower-cost VX330T or VX485T FPGAs can be installed.

The 78720 supports Gen 3.0 PCI Express as the primary control and data-streaming interface. With lane widths up to x8, data can be moved on and off the board at rates up to 8 GB/sec. Such rates are invaluable for moving the full-bandwidth, multichannel data required in many applications.

The Onyx architecture includes GateXpress, a sophisticated FPGA-PCIe configuration manager for loading and reloading the FPGA. At power-up, GateXpress immediately presents a PCIe target for the host computer to discover, effectively giving the FPGA time to load from FLASH. This is especially important for larger FPGAs where the loading times can exceed the PCIe discovery window, typically 100 msec on most PCs.
