UI
Jitter is defined as the measurement variation of the
crossing points (VTX-DIFFp-p = 0 V) in relation to a
recovered Tx UI. A recovered Tx UI is calculated over
3500 consecutive unit intervals of sample data. Jitter is
measured using all edges of the 250 consecutive UI in
the center of the 3500 UI used for calculating the Tx UI.
