Differential Receiver (RX) Input Specifications
Table 60 defines the specifications for the differential input at all receivers (RXs). The parameters are
specified at the component pins.

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.

UI
Jitter is defined as the measurement
variation of the crossing points (VRX-DIFFp-p
= 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.
