2-channel 1000MSPS PMC DAC


The AD481 is a high performance PMC waveform generator module dedicated to digital signal processing applications with high bandwidth and complex algorithms requirements. In addition to two 1GSPS (1000MSPS) A/D channels, the AD481 offers fast on-board memory resources and two Virtex-4 FPGAs. Up to 4x 2.5Gbps optical tranceivers for serial FPDP or gigabit Ethernet applications are available for communication with external systems (eg, storage system).
