Phase Jitter
This is the jitter amplitude in unit intervals (UI) as a
function of jitter frequency.
Range
10 UI p-p from 20 Hz to 500 Hz, decreasing
proportionally to 0.5 UI p-p from 10 kHz to 50 kHz
Accuracy
For sinusoidal jitter greater than –20 dBUI
(0.1 UI p-p) at jitter gain = 1, or greater than
–40 dBUI (0.01 UI p-p) at jitter gain = 8
Jitter Gain = X1 or X8
