I would like to use a signal generator as an external oscillator for two FMCOMMS3. I am using two FMCOMMS3 boards and connecting them to a ZC702 evaluation board. I would like to sync the clocks of the two SDRs so I want to use an external oscillator and a splitter to accomplish this task.
What are the steps needed to make this happen? How do I tell the device to use the external oscillator instead of the crystal on the board? The Analog Devices website/AD9361 datasheet is extremely vague on how to actually implement an external oscillator. It only mentions that it is possible.
Thank you for your help in advance!
