I want to use ad9164-fmc-ebz with external dac clock.
After checking the diagram of this module, I found that the external dac clock is routed to the DAC chip directly. At the same time, the ref clock, which the FPGA need, is generated by ADF4355.
As I know, the ref clock should be coherent with the DAC clock, or the 204B link will not work.
So here is my question: how to achieve the coherency of these clocks?
