About the clock, we can find below description at the website, https://www.wiki.analog.com/resources/eval/user-guides/ad-fmcomms5-ebz/hardware/configuration_options
But I have not found any information about the RX03225M by google. Could you please help to tell the crystal part number and coresponding information? Thanks.
By default the FMComms5 uses a Rakon 40MHz RX03225M as the reference clock. This is driven into the ADCLK846, which distributes the clock to the two AD9361s, the ADF5355, as well as back to the FMC connector. It is important that the PCB trace lengths to the two AD9361s be equally matched.
