I am trying to get the AD9129 working on a KCU105 board. I got almost everything working (verified signal via o-scope), but I am unable to get the DLLs phase to lock properly. Everytime I read 0x0E, I get a response of 0x85. I have odelay blocks (FPGA) on the DCI line and it is software programmable. I have incremented every value for the delay block, and I changed the DCI's phase by 45 degree increments. I just can't get the DLL's phase to be correct.
Can anyone help? danf have any suggestion?
