Description
FMC-DAQ2P5 allows for ADC decimation and DAC interpolation. External trigger input allows the addition of timestamps to the sample stream from ADC. CLK-IN can be a Sample clock input up to 4GHz, or a reference clock input up to 1GHz. The module provides simultaneous working of ADC and DAC on a sample rate of 2.1GSPS, using an internal VCXO clock.
FMC-DAQ2P5 provides 4 x high-speed transceiver lanes routed from the FPGA carrier card to the bezel. 4 differential low-speed lanes and 10 single-ended IO are also routed to the Molex connector available at the bezel which, can be used for any control or data exchange with the FPGA.
