Minimum time spent in
electrical idle
TTX-IDLE-MIN
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

Maximum time to
transition to a valid
electrical idle after
sending an electrical idle
ordered set
TTX-IDLE-SET-TO-IDLE 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
transition to valid TX

an electrical idle condition
TTX-IDLE-TO-DIFF-DATA 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
