2.5GSps 10-Bit ADC 12-Bit DAC for WFMC+ – WWSM20
This ultra low latency 2.5GSps 10-Bit ADC 12-Bit DAC for WFMC+ is specifically designed for DRFM applications with 21ns latency from SMA to SMA.
Compatible with any WILDSTAR mainboard with a WFMC+ slot.
The 2.5GSps 10-Bit ADC 12-Bit DAC for WILD FMC+ 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 Fabric Space Mode adds only 21ns of latency. 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 a 21ns latency DRFM-optimized application in minutes.
The 2.5GSps 10-Bit ADC 12-Bit DAC for WILD FMC+ 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 2.5GSps 10-Bit ADC 12-Bit DAC for WILD FMC+ provides high fidelity and high speed analog-to-digital conversion along with a rugged design.
