Ratio of the V
bits after a transition divided by the V
first bit after a transition. See Note 2.
The maximum Transmitter jitter can be derived as
T
See Notes 2 and 3.
Jitter is defined as the measurement variation of the
crossing points (V
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 and 3.
