WLDM30


Overview

COTS ADC and DAC Card

This ultra-low-latency COTS ADC and DAC Card from Annapolis Micro Systems is designed for DRFM and other latency-sensitive applications. Compatible with any WILDSTAR mainboard with a WILD Mezzanine Card LVDS (WMC-L) Site.

Technical

The WILD WLDM30 ADC & DAC LVDS is designed from the ground up for ultra-low latency from ADC SMA input to DAC SMA output. The Board Support Interface, which is available in VHDL or Open CoreFire Next Application Design Suite, allows the user to design an ultra-low latency DRFM-optimized application in minutes.

Single channel 12-bit ADC/DACs run at up to 6.4GSps each, or two channels at up to 3.2GSps each.
 

Specifications

General
  • Dual Channel 12-bit ADC/DAC running at up to 3.2GSps each
