t_JITD(PP) Peak-to-peak output residual data jitter
AVCC = 3.3 V, R_T = 50 Ω. See Figure 11.
AVCC = 3.3 V, R_T = 50 Ω, dR = 2.25 Gbps.
See Figure 14 for measurement setup;
residual jitter is the total jitter measured at
TTP4 minus the jitter measured at TTP1. See
Figure 15 for the loss profile of the cable used
for t_JITD(PP) measurement. Also see Typical
Curves for t_JITD(PP) across cable length and
input TMDS data rate.

(1) All typical values are at 25°C and with a 3.3-V supply.
(2) t_sk(p) is the magnitude of the time difference between t_PLH and t_PHL of a specified terminal.
(3) t_sk(o) is the magnitude of the difference in propagation delay times between any specified terminals of a sink-port bank when inputs of
the active source port are tied together.
