WILDSTAR 3XR2 3U OpenVPX FPGA Processor – WB3XR2

The WILDSTAR 3XR2 FPGA Processor is 100GbE-enabled, SOSA-aligned, and it leverages the processing and A/D & D/A converting power of two Gen 3 Xilinx UltraScale+™ RFSoC FPGAs. Plus, the 3XR2 offers a full-length coax-connected Analog Interface Mezzanine Site. See below for the benefits of this Site.

Need the same SOSA-alignment and 100GbE capability in a 6U VPX form factor? See the WILDSTAR 6XB2 6U OpenVPX Board.

These FPGA boards are SOSA-aligned Plug-In Cards (PIC). They offer an Analog Interface Mezzanine Site that can be populated with an Annapolis or 3rd party/customer-designed RF Card 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.
