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 tJITD(PP)
measurement. Also see Typical Curves for
tJITD(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) tsk(p) is the magnitude of the time difference between tPLH and tPHL of a specified terminal.
(3) tsk(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.
