Hitech Global has announced the HTG-728 100G NIC (network interface card) PCIe Gen3 board based on the Xilinx Virtex-7 H580T FPGA. On board, there’s a CFP2 (4x25Gbps) and a CFP4 (4x25G) card cage for optical Ethernet modules. In addition, for board-to-board and other in-box system interconnect, there are two Avago MiniPOD optical receiver/transmitters, each with twelve TX and RX lanes for an aggregate bandwidth of 120Gbps in addition to the board’s x16 PCIe Gen3 interface.

Clearly, the board is extracting a lot of benefit from the Virtex-7 H580T FPGA’s eight 28.05Gbps GTZ and forty-eight 13.1Gbps GHT SerDes ports.
