AD8134
APPLICATIONS
DRIVING RGB VIDEO OVER CAT-5 CABLE
The AD8134 is a device whose foremost application is driving
RGB video signals over UTP cable in KVM 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. The AD8134 can be used in all of
the typical KVM network topologies, including daisy-chained,
star, and point-to-point. Figure 33 shows the AD8134 in a
triple, single-ended-to-differential application in a daisy-
chained network when driven from a 75 Ω video source.
