2-channel 210MSPS PMC digitizer


The AD490 is a high performance PMC digitizer module dedicated to digital signal processing applications with high bandwidth and complex algorithms requirements. In addition to two 210MSPS A/D channels, the AD490 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).
