WWSM21

Overview

The WILD FMC+ SM21 ADC & DAC from Annapolis Micro Systems was designed from the ground up for latency-sensitive DRFM applications. The Board Support Interface, which is available in VHDL or CoreFire Next Application Design Suite, 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 Board Support Interface also includes a built-in Bypass Delay which can be controlled to be from 0 to 124 ADC sample clock periods, with each step equaling 4 Fs periods. 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.

The CoreFire Next Design Suite, Annapolis’ FPGA Design Tool, allows the user to design an ultra-low latency DRFM-optimized application in minutes.
The WILD FMC+ SM21 ADC & DAC 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 WILD FMC+ SM21 ADC & DAC provides high fidelity and high-speed analog-to-digital conversion along with a rugged design.
