AD491 Dual Channel 1GSPS PMC/XMC Digitizer
Description
The AD491 is a high performance PMC/XMC digitizer module dedicated to digital signal processing applications with high bandwidth and complex algorithms requirements. In addition to two 1GSPS (1000MSPS) A/D channels, the AD491 offers fast on-board memory resources and two Virtex-4 FPGAs. Up to 4x 2.5Gbps optical transceivers for serial FPDP or gigabit Ethernet applications are available for communication with external systems (e.g., storage system).
