Differential Receiver (RX) Input Specifications
Table 50 defines the specifications for the differential input at all receivers (RXs). The parameters are
specified at the component pins.

Each UI is 400 ps ± 300 ppm. UI does not
account for Spread Spectrum Clock dictated
variations. See Note 1.

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 2 and 3.
TRX-EYE-MEDIAN-to-MAX

median and
maximum
deviation from
the median.

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.
