The total amount of voltage change that a
transmitter can apply to sense whether a
low impedance receiver is present. See
Note 6.
The allowed DC common mode voltage
under any conditions. See Note 6.
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 LO.
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. See
Note 4.
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.
