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:
However，for 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?

Check this for the phase noise mask:

For example, an oscillator datasheet gives the stability (use ppm as a unit) only below:
so ,if I choose it as the clock source for PL HDGC/GC, or PS reference clock, or PS_MGTREFCLK, how can I know whether it meets the requirement?
