Each UI is 400 ps ± 300 ppm. UI does not
account for Spread Spectrum Clock
dictated variations. See Note 1.
V
See Note 2.
The maximum interconnect media and
Transmitter jitter that can be tolerated by the
Receiver can be derived as T
= 1 - T
See Notes 2 and 3.
Jitter is defined as the measurement
variation of the crossing points (V
= 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.

Measured over 50 MHz to 1.25 GHz with
the D+ and D- lines biased at 0 V. See Note
