This high density WILD FMC+ GM60 ADC & DAC is the industry’s first COTS FMC+ Mezzanine to feature the new Xilinx® Zynq® UltraScale+™ RF System-on-Chip (RFSoC) technology. The flexible RFSoC device can support many different configurations and combinations of ADCs and DACs.

The GM60 provides 4 channels each of ADC and DAC.

The GM60 is available for use with Annapolis’ WILDSTAR PCIe and OpenVPX Baseboards. Also designed for standalone use, the GM60 is designed for applications limited by Size, Weight, Power, and Cost (SWaP-C). This WILD FMC+ card operates within a tight envelope; it is slimmer than a 3U OpenVPX board, with about 45% less depth.

The versatile GM60 is ideal for advanced High Performance Computing (HPC), Radar, and Electronic Warfare (EW) applications, including DRFM, beamforming, sensor processing, wireless communication, and radar signal processing.

The GM60’s integrated Xilinx RFSoC combines FPGA processing and A/D and D/A Converters in a single chip, giving the board remarkable density and performance:

  • 4-Channel 4.0GSps 12b ADC
  • 4-Channel 6.4GSps 14b DAC

Also available:

  • 2 ADC & 8 DAC Channels – WWGM61
  • 8 ADC & 2 DAC Channels – WWGM62
  • 4 ADC & 4 DAC Channels – WWGM63

The RFSoC also includes a multi-processor embedded ARM® Cortex-A53 Application Processing Unit (APU) and an ARM Real Time Processing Unit (RPU).

The GM60  provides high fidelity and high speed analog-to-digital and digital-to-analog conversion along with a rugged design.

For large deployments requiring significant processing capability, synchronize multiple RFSoC cards.

The GM60 is shipped with a custom heatsink which enables proper cooling of the ADC. An on-board temperature monitor is also supplied which allows for real-time monitoring of the ADC’s internal die temperature.

The Board Support Interface is available in VHDL or CoreFire Next Application Design Suite.
