APPLICATIONS
DRIVING RGB VIDEO SIGNALS OVER CATEGORY-5
UTP CABLE
The foremost application of the AD8133 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 common topologies used in KVM
networks, such as daisy-chained, star, and point-to-point, are
supported by the AD8133. Figure 36 shows the AD8133 in a
triple single-ended-to-differential application when driven from
a 75 source, which is typical of how RGB video is driven over
an UTP cable. In applications that use the OPD feature, the
Schottky diodes are placed in series with each of the 49.9
resistors in the outputs.
