Xilinx Virtex UltraScale+ HBM VU37P Power and Timing

One of Xilinx’s latest families of FPGAs is the Virtex® UltraScale+™ HBM. This family is targeted for very high-performance applications in computing, storage and networking. It features Xilinx’s highest on-chip memory density, with total on-chip integrated memory up to 500Mb, and high-bandwidth memory (HBM) up to 16GB. It also supports PCIe® Gen4 and transceivers up to 32.75Gb/s.

An FPGA with this level of performance demands a high-current power supply with tight regulation and extremely low jitter clock sources. This winning combination highlights the power devices that Xilinx chose for their own reference design called the VCU128 and recommends two clocking devices that would be an excellent fit for many designs.
