FMC DAC 600M 12b 1cha DDS

FMC DAC 600M 12b 1cha DDS

The FMC DAC 600M 12b 1cha DDS board can be used to distribute RF signals over the White Rabbit network

Description

The idea of RF distribution over WR is described in the Distributed Direct Digital Synthesis over White Rabbit (D3S) project.
Together with the Simple PCIe FMC Carrier - SPEC this board makes a complete WR RF distribution node.
