 The AD-FMCOMMS2-EBZ and AD-FMCOMMS3-EBZ are both clocked from a 40.000000 MHz Epson crystal. If you want to run from a external source, you need to remove Y101, populate C113 (0.1uF Cap), and provide a low jitter clock source into J105 (SMA connector). If you provide anything but a 40.000000 MHz input, you are required to change the ''clock-frequency'' setting in the device tree. The AD-FMCOMMS2-EBZ and AD-FMCOMMS3-EBZ are both clocked from a 40.000000 MHz Epson crystal.
