VTX-RCV-DETECT
Amount of voltage
change allowed during
receiver detection
—
600
mV
The total amount of voltage change that a
transmitter can apply to sense whether a
low impedance receiver is present. See
Note 6.
VTX-DC-CM
TX DC common mode
voltage
0
—
3.6
V
The allowed DC common mode voltage
under any conditions. See Note 6.
ITX-SHORT
TX short circuit current
limit
—
90
mA
The total current the transmitter can
provide when shorted to its ground.
TTX-IDLE-MIN
Minimum time spent in
electrical idle
50
—
UI
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.
TTX-IDLE-SET-TO-IDLE
Maximum time to
transition to a valid
electrical idle after
sending an electrical
Idle ordered set
—
20
UI
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.
TTX-IDLE-TO-DIFF-DATA
Maximum time to
transition to valid TX
specifications after
leaving an electrical
idle condition
—
20
UI
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.
RLTX-DIFF
Differential return loss
12
—
dB
Measured over 50 MHz to 1.25 GHz. See
Note 4.
RLTX-CM
Common mode return
loss
6
—
dB
Measured over 50 MHz to 1.25 GHz. See
Note 4.

80
100
120
Ω
TX DC differential mode low impedance.
ZTX-DC
Transmitter DC
impedance
40
—
Ω
Required TX D+ as well as D– DC
Impedance during all states.
LTX-SKEW
Lane-to-lane output
skew
—
500 +
2 UI
ps
Static skew between any two transmitter
lanes within a single link.
CTX
AC coupling capacitor
75
—
200
nF
All transmitters shall be AC coupled. The
AC coupling is required either within the
media or within the transmitting component
itself.
