(1) The HDMI cable between TTP1 and TTP2 is 0 m (no loss) case and 20 m case. See Figure 15 for the loss profile of
the cable.
(2) All jitter is measured at a BER of 10
–9
.
(3) Residual jitter reflects the total jitter measured at TTP4 minus the jitter measured at TTP1.
(4) AVCC = 3.3 V; VSadj = 4.02 kΩ.
(5) R
T
= 50 Ω.
(6) 2 inches = 5,08 cm.
NOTES: Output edge rate default (fastest): input edge rate from the parallel BERT greater than 75 ps (20%–80%). The input
signal from the parallel BERT has no pre-emphasis.
