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.

See Note 2.
Measured over 50 MHz to 1.25 GHz with the
D+ and D– lines biased at +300 and
–300 mV, respectively. See Note 4.
Measured over 50 MHz to 1.25 GHz with the
D+ and D– lines biased at 0 V. See Note 4.
RX DC differential mode impedance. See
Note 5.
Required RX D+ as well as D– DC
impedance (50 ± 20% tolerance).
See Notes 2 and 5.
Required RX D+ as well as D– DC
impedance when the receiver terminations
do not have power. See Note 6.
V
Measured at the package pins of the
receiver.
An unexpected electrical idle (V
< V
no longer than T
signal an unexpected idle condition.
