Ratio of the V
after a transition divided by the V
bit after a transition. See Note 2.
The maximum Transmitter jitter can be derived as
T
See Notes 2 and 3.
Jitter is defined as the measurement variation of the
crossing points (V
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.

The total amount of voltage change that a transmitter
can apply to sense whether a low impedance receiver
is present. See Note 6.
The allowed DC common mode voltage under any
conditions. See Note 6.
The total current the transmitter can provide when
shorted to its ground
Minimum time a transmitter must be in electrical idle.
Utilized by the receiver to start looking for an electrical
idle exit after successfully receiving an electrical idle
ordered set.
