The total amount of
voltage change that a
transmitter can apply to
sense whether a low
impedance Receiver is
present.
The allowed DC Common
Mode voltage under any
conditions.
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
