FPGA Based Cards

fb4CGg3@VU series FPGA Card

Quad Port QSFP28 100 Gigabit Xilinx® Virtex Ultrascale

The fb4CGg3@VU/VU+ series is a high performance OEM hardware platform intended for 10/40/25/50/100 Gigabit Ethernet via its quad QSFP28 slots.

The standard configuration is based on the Xilinx® Virtex UltraScale+ VU9P FPGA, to provide ample capacity for the quad QSFP28 interface.
The card is also offered with a variety of different FPGAs to provide flexibility for the intended application – this includes both Virtex Ultrascale and the Virtex Ultrascale+ series from Xilinx.
