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 ordered set
After sending an Electrical Idle ordered
set, the Transmitter must meet all
Electrical Idle Specifications within this
time. This is considered a debounce time
for the Transmitter to meet Electrical Idle
after transitioning from L0.
Maximum time to meet all TX
specifications when transitioning from
Electrical Idle to sending differential
data. This is considered a debounce
time for the TX to meet all TX
specifications after leaving Electrical Idle
