Honored ContributorCalculating jitter
I see a PLL output jitter spec of 25mUI for clocks less than 100MHz. Does anyone know how to calculate the output jitter with this spec?

Altera_ForumUI is unit interval, which is the period of your clock in this case. mUI is 0.001UI. Based on that you can calculate your jitter for whatever period clock you have.

25x10ˆ-3 (10ns) = 250ps
Where 10ns is the period of the clock you are using.
