ADC & DAC Mezzanine Cards for DRFM

Ultra-Low Latency DRFM-Optimized ADC and DAC Mezzanine Cards have been designed from the ground up for latency sensitive DRFM solutions. The Board Support Interface, which is available in VHDL or Open Project Builder, was also designed from the beginning to be suited for DRFM applications. This interface provides a Digital Bypass Mode to achieve the lowest possible latency and a Fabric Space Mode to allow the user to do additional processing and manipulation of the ADC data before returning it out the DAC. The Fabric Space Mode adds as little as 13ns of latency. The Board Support Interface also includes a built-in Bypass Delay. This allows the user to “walk” the latency out from the minimum Digital Bypass Mode latency to slightly beyond the Fabric Space Latency, providing for a smooth latency transition between the two modes.

Open Project Builder, Annapolis’ FPGA Design Tool, allows the user to design a DRFM-optimized application in minutes.
