AD9520-4 EVB's phase noise is too high

plkmn3 on Dec 24, 2015

Hi;

We have a evb of ad9520-4, we use a 10MHZ ref from R&S spectrometer and config the evb to output a 50MHZ signal. According to ADIsimCLK, we should got a phase noise around -130dBc/Hz at 50KHz offset, but accually we got only -105dBc/Hz. The loop components is as the evb shipped, we didn't modify them, and cp current set to 600uA.

Could you please give some advice to improve it?

THX!
