How to choose clock oscillators as the clock inputs for PS reference clock?

Hello,

In my design, I want to use several clock oscillators as the clock inputs for PS reference clock, PS_MGTREFCLK and PL HDGC/GC of ZU9EG. However, in DS925, it only gives the clock jitter value:

Howeverfor choosing oscillators, I must know the requirement for the total stability (use ppm as a unit) of PS reference clock, PS_MGTREFCLK and PL HDGC/GC. So where can I find the requirement?

Hi,

Check this for the phase noise mask:
