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.
See Note 4.
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. See note
8.
