I think it was mostly related to the levels and coupling, possibly combined with the 13 MHz signal being a sine wave and not square whihc I believe the TI PLL expects.
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?
