V
The maximum interconnect media and transmitter
jitter that can be tolerated by the receiver can be
derived as T
See Notes 2 and 3.
Jitter is defined as the measurement variation of
the crossing points (V
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.
