fb4XG@V6240 FPGA Card

Quad Port SFP+ 10 Gigabit Ethernet FPGA Card

The fb4XG@V6240 is a high performance OEM hardware platform for 10G Ethernet with quad port SFP+ network interface.

The standard configuration is based on Xilinx Virtex6 LX240T FPGA. The card is also offered with a variety of different FPGAs to provide flexibility for the intended application.

As an optional feature, the card can be fitted with two SATA connectors which can provide connectivity to a wide range of standard storage devices directly to the FPGA card.
