WILDSTAR G2 Dual 1.5 GSps 12-Bit ADC & DAC Mezzanine Card

This ultra low latency WILDSTAR G2 Dual 1.5 GSps 12-Bit ADC & DAC Mezzanine Card is specifically designed for DRFM applications.

Compatible with WILDSTAR™ 7 and WILDSTAR A5 mainboards.

Dual Channel 1.5GSps 12-Bit ADC & DAC Mezzanine Card

The WILDSTAR G2 Dual 1.5 GSps 12-Bit ADC & DAC Mezzanine Card was designed from the ground up for latency sensitive DRFM applications. The Board Support Interface, which is available in VHDL or CoreFire 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 62 ADC sample clock 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 industry is already talking about the ultra low latency that is achievable in this COTS product:

The new IOADCDACD1.5G mezzanine card from Annapolis Micro Systems was built specifically for use as a DRFM, and it has some impressive specs. Its two analog input and output channels have around 600 MHz instantaneous bandwidth each, which is respectable and covers a good range of applications. The board’s latency, though, is where it really shines. This makes it well suited to self-protection applications. Its board support package is also designed to make the integration of a user’s DRFM kernel simple, which should be refreshing to anyone who has had to build a DRFM out of an FPGA board that wasn’t really designed to be one.”

The WILDSTAR G2 Dual 1.5 GSps 12-Bit ADC & DAC Mezzanine Card 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 WILDSTAR G2 Dual 1.5 GSps 12-Bit ADC & DAC Mezzanine Card provides high fidelity and high speed analog-to-digital conversion along with a rugged design.
