WILDSTAR Radial Clock Distribution Board – WP6C20

The WILDSTAR™ Radial Clock Distribution Board allows for synchronization of up to 20 ADC/DAC WFMC+ per Clock Board.


The WILDSTAR Radial Clock Distribution Board allows for synchronization of up to 20 ADC/DAC WFMC+ per Clock Board, with 10 differential radial REFCLK outputs, 10 differential radial AUXCLK outputs, and optional 20 single-ended clock outputs.

The Board is powered by a Xilinx Zynq UltraScale+ MPSoC CG Motherboard Controller.

It is 6U OpenVPX compliant and supported for air- or conduction-cooled environments.
