LMK05028EVM: No lock problem

Part Number: LMK05028EVM
Other Parts Discussed in Thread: LMK05028

Hi Team,

 

Sorry for sending you frequent question, however I need

your advice to resolve my No Lock problem.

 

With your advice I could make LMH05028EVM lock to a 25 MHz input.

So, I tried to make the EVM get lock to the 67.25 kHz input and create 148.5 MHz,

Or lock to 67.5/1.001 kHz input and create 148.5/1.001 MHz, but EVM did not

Lock to either of the input.

I attached to design files dedicated to 67.5 kHz input and 67.5/1.001 kHz.

Can you check these design files and give me your advice.

I also have one more question,.

I tried to modify parameters in User Controls => DPLLx CTL page,

but none of them can’t be changed.

Please advise me on how to change values in User Controls => DPLLx CTL page,
