FB4CGG3@VU/VU+ series

FPGA Card – 100G Quad FPGA Card QSFP28 port supporting 4x100GE, 16xPCIe Gen3

FPGA Card – Quad QSFP28 port card supporting 4x100GE, 16xPCIe Gen3, AMD® Virtex Ultrascale/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 AMD® 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 AMD®.

The card is mounted with 2 x 64-bit DDR4 2400MT/s 4GB for a total of 8 GB. In addition to this it features 2 SODIMM sockets for use with DDR4 or QDRII+ modules for low latency applications.
