Applies to both 3.3V
and 5V pull up resistors.
Comments
Normal Tbit at 2.7Gb/
s=370ps. 333ps=370ps-
10%
VRX-DIFFp-p =
2*|VRX-D+ - VRX-D-
|. Applies to IN_D and
RX_IN signals.
Jitter budget for high-
speed signals as they
pass through the display
mux.
7.4ps = 0.02 Tbit at
2.7Gb/s
For example, ≥-1.5 dB
at f = 1.35 GHz
For example, ≥-4.5 dB
at f = 2.7 GHz
Comments
Low-speed input chang-
es state on cable plug/
unplug.
V
Measured with HPD
at VIH-HPD max and
VIL-HPD min
Time from HPD_IN
changing state to HPD
changing state. Includes
HPD rise/fall time.
Time required to transi-
tion from VOH-HPD to
VOL-HPD or from
VOL-HPD to VOH-
HPD.
