APPLICATIONS INFORMATION
DRIVING RGB VIDEO OVER CAT-5 CABLE
The AD8141 and AD8142 are devices whose foremost application
is driving RGB and component video signals over unshielded
twisted pair (UTP) cable in video distribution networks. Single-
ended video signals are easily converted to differential signals
for transmission over the cable, and the internally fixed gain of 2
automatically compensates for the losses incurred by the source
and load terminations. Figure 42 shows the AD8141/AD8142 in
a triple, single-ended-to-differential application when driven from
a 75 video source.
