As I understand the datasheet of the CDCVF25084 it can
very well be the
case that a sine wave input makes trouble.
Assuming this is the case, could something like a Schmitt trigger
between the sine wave source and the PLL improve the situation?
Or would that add jitter or some other negative effects to the signal?
