I was working with the evaluation board, and things seem to be working correctly.
The board seemed to deteriorate from "locked" but with a frequency 5MHZ off from the desired frequency. Now I am not seeing any lock at all.
Is there some insight about what could be causing it not to lock? I have a precision clock feed to the SMA connector, and I have checked power and SPI registers and nothing looks wrong. Is it possible that the board was damaged by my probing?
I have populated this device on our prototype and I am able to see a lock on the our prototype board. However, I am only able to achieve lock by holding the ENBL on all the time. This is not feasible for our final design. I believe on the eval board (before it stopped working) after it locked initially I could turn it on/off via the switch. I can provide any additional information if needed via email.
