UI The maximum interconnect
media and Transmitter jitter that can
be tolerated by the Receiver can be
derived as TRX-MAX-JITTER =
1 - TRX-EYE = 0.6 UI.
See Notes 8, 9, and 10.

UI Jitter is defined as the measurement
variation of the crossing points
(VRX-DIFFp-p = 0 V) in relation
to a recovered TX UI. To be
measured after the clock recovery
function.
See Notes 8 and 9.
