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
Measured over 50 MHz to
1.25 GHz.
Measured over 50 MHz to
1.25 GHz.
TX DC Differential mode Low
Impedance
Required TX D+ as well as D-
DC Impedance during all
states
Static skew between any two
Transmitter Lanes within a
single Link
All Transmitters shall be AC
coupled. The AC coupling is
required either within the
media or within the
transmitting component itself.
