Hello,

There are the unexptected pulse at the parallel data out of DS90UB914A-Q1 on the PLL Lock condition.
The pulse is not appeared at the parallel data in of DA90UB913A-Q1.

Could you please let me know the possibility cause of this?
Please let me know what we should confirm.

I think that the parallel input waveform is same with the parallel output waveform as far as PLL is locked.

Best Regards,
