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. See
Notes 2, 3 and 7.
