AD481 Dual Channel 1000MSPS PMC/XMC Waveform Generator

Description

The AD481 is a high performance PMC/XMC waveform generator module dedicated to digital signal processing applications with high bandwidth and complex algorithms requirements. In addition to two 1GSPS (1000MSPS) D/A channels, the AD481 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).
