BittWare XUP-VV4 FPGA Accelerator Card

BittWare XUP-VV4 FPGA Accelerator Card features the UltraScale+ VU13P FPGA and is ideal for high-density datacenter applications. The Xilinx UltraScale+ VU13P FPGA gives designers incredible performance potential with 3.8M logic elements. Thought this offers a power density that makes thermal management difficult. The XUP-VV4 rises to the challenge with BittWare’s Viper platform, supporting large FPGA loads, up to 512 GBytes DDR4, and 4x 100Gbps Ethernet. BittWare’s Viper platform uses advanced computer flow simulation to drive the physical board design in a thermals first approach. This includes the use of heat pipes, airflow channels, and arranging components to maximize the limited available airflow in a server.

The BittWare XUP-VV4 FPGA Accelerator Card features air cooling by default, but liquid cooling is also available. The device provides the Xilinx D2104 lidless package, allowing the heat pipes to contact the die directly, instead of through the heat spreader lid.
