BittWare XUP-VV8 FPGA Accelerator Card

BittWare XUP-VV8 FPGA Accelerator Card features the Xilinx FPGA in a 3/4-length PCIe board, including QSFP-DD (double-density) cages for maximum port density. The XUP-VV8 supports up to 8x 100GbE or 32x 10/25GbE using the Virtex UltraScale+ VU13P or VU9P FPGA. The FPGA provides large logic resources up to 3.8M logic cells, as well as 455Mb of embedded memory.

The BittWare XUP-VV8 FPGA Accelerator Card offers a jitter cleaner to support synchronous ethernet. If external memory on the DIMMs is not required, the board can be configured as single width.
