TTX-EYE-MEDIAN-to-
MAX-JITTER
Maximum time
between the jitter
median and maximum
deviation from the
median.
0.15
UI
Jitter is defined as the measurement
variation of the crossing points (VTX-DIFFp-p
= 0 V) in relation to a recovered TX UI. A
recovered TX UI is calculated over 3500
consecutive unit intervals of sample data.
Jitter is measured using all edges of the
250 consecutive UI in the center of the
3500 UI used for calculating the TX UI. See
Notes 2 and 3.

See Notes 2 and 5.
VTX-CM-ACp
RMS AC peak
common mode output
voltage
20
mV
VTX-CM-ACp = RMS(|VTXD+ –
VTXD–|/2 – VTX-CM-DC)
VTX-CM-DC = DC(avg) of |VTX-D+ –
VTX-D–|/2
See Note 2.
VTX-CM-DC-ACTIVE-
IDLE-DELTA
Absolute delta of DC
common mode voltage
during LO and
electrical idle
0100
mV
|VTX-CM-DC (during LO) – VTX-CM-Idle-DC
(During Electrical Idle)|<= 100 mV
VTX-CM-DC = DC(avg) of |VTX-D+ –
VTX-D–|/2 [LO]
VTX-CM-Idle-DC = DC(avg) of |VTX-D+ –
VTX-D–|/2 [Electrical Idle]
See Note 2.
VTX-CM-DC-LINE-DELTA Absolute delta of DC
common mode
between D+ and D–
025
mV
|VTX-CM-DC-D+ – VTX-CM-DC-D–| <= 25 mV
VTX-CM-DC-D+ = DC(avg) of |VTX-D+|
VTX-CM-DC-D– = DC(avg) of |VTX-D–|
See Note 2.
VTX-IDLE-DIFFp
Electrical idle
differential peak output
voltage
020
mV
VTX-IDLE-DIFFp = |VTX-IDLE-D+ – VTX-IDLE-D–|
<= 20 mV
See Note 2.
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.
