Honored ContributorQuestion about PLL's output jitter
I found below comment from device's datasheet: "250 ps for >= 100 MHz coutclk. 25 mUI for <100 MHz outclk" Here, how to understand "mUI"?

Honored ContributorJust googled it and it says mUI is milli Unit interval.
Thus for the case of >100MHz jitter is fixed to 250 ps irrespective of clock speed. For < 100MHz it is tied up to clock speed as unit interval/1000. Unit interval here is clock period.
