WILDSTAR 3XVR 3U OpenVPX FPGA Processor – WS3XVR
The WILDSTAR 3XVR FPGA Processor is 100GbE-enabled, SOSA-aligned, and it leverages the processing and A/D & D/A converting power of an AMD Versal RF FPGA.
Want the same Direct RF sampling capability in an even smaller form factor? See all of our Small Form Factor Solutions.

These SOSA-aligned Plug-In Cards (PIC) offer many channels and high ADC/DAC sample rates that are integrated into the FPGA. Choose from one of four Versal RF FPGAs: VR1602, VR1652, VR1902, or VR1952.
This board also includes an Analog Interface Mezzanine Site. This can be populated with Annapolis or 3rd party/customer-designed RF Cards for front-end personalization (e.g. pre-filtering or analog conditioning) for applications of interest.
Annapolis’ powerful BSP options include 40/100GbE IP and Linux support.
