The MAX7474 evaluation kit (EV kit) is a fully assem-
bled and tested printed-circuit board (PCB) that config-
ures the MAX7474 IC for automatically equalizing a
baseband composite video input signal from low-cost,
unshielded twisted pair (UTP) such as Category 5e
(Cat 5e) cable.
The MAX7474 EV kit operates from a single 5V DC
power supply. The EV kit accepts differential video
input signals and provides a single-ended output. The
EV kit features loss-of-sync and loss-of-burst outputs
and also provides an option to set the video output sig-
nal’s back-porch DC level.
