Preliminary Technical Data
The length of cable that can be used in a typical HDMI/DVI
application depends on a large number of factors including:
•
•
•
Cable quality: the quality of the cable in terms of conductor
wire gauge and shielding. Thicker conductors have lower
signal degradation per unit length.
Data rate: the data rate being sent over the cable. The signal
degradation of HDMI cables increases with data rate.
Edge rates: the edge rates of the source input. Slower input
edges result in more significant data eye closure at the end
of a cable.

•
As such, specific cable types and lengths are not recommended
for use with a particular equalizer setting. In nearly all applica-
tions, the AD8191 equalization level can be set to high, or 12 dB,
for all input cable configurations at all data rates, without
degrading the signal integrity.
Receiver sensitivity: the sensitivity of the terminating
receiver.
