Minimum time spent in
electrical idle
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.

Maximum time to
transition to a valid
electrical idle after
sending 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
LO.
