Jitter is defined as the
measurement variation of the
crossing points (V
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.
