Can I join this private message because I facing the same problem?

With some IOD not all FOD's generate correct frequencies.

We use 2 output clocks and the same combination IOD/FOD works on the first output and not on the other or vice versa.

Even on the boards which generates the correct frequency, jitter is very bad resulting in malfunctioning of our design.

We have tested it on 20 boards and the issue occurs on more then 4 boards.
