Question:
The external clock input on the AD9164-FMC-EBZ isn't working. ACE software selects to change it, but nothing happens on the eval board.
Resolution:
This is a known issue with boards that were produced near release time. The firmware programmed on the eval board does not toggle the control signal for the RF switch, making it such that the eval board will always use the on-board clock and won't use the external clock. This applies to AD9162-FMC-EBZ, AD9164-FMC-EBZ, and may apply to the AD9162-FMCB-EBZ and AD9164-FMCB-EBZ that have B-grade released parts loaded on them with date codes #1615. The issue applies to a small number of boards. The boards must be re-programmed at the factory with correct firmware. The customer should arrange return of the board with the local ADI support person (FAE or TSM), who should contact the ADI factory and arrange the return, re-program, and re-ship back to the customer.
