We ordered the AD-FMCOMMS1-EBZ and try to configure the AD9523 to output 768Mhz clock. However no mater how I programming the board, it always output the 122.88Mhz. We have 122.88Mhz oscillator on board. Also we tried to lock the ad9548 to external 10Mhz, however it failed to do so.
Is there any recommendation or reference design how to configure the board to this frequency? And where I could find the GUI and driver to connect the board by USB cable to set up the board using PC?
Please find the register map snapshot attached.
