Adaptive Equalizer for

of monitors or recording devices. Cabling is a signifi-
cant part of a CCTV installation cost. Low-cost
unshielded twisted-pair (UTP) cable has increasingly
replaced coaxial cable in security systems. Most cam-
eras and switchers use single-channel coax connec-
tors,
and
therefore
require
some
type
of
single-ended-to-differential video conversion such as
active drivers. Active cable compensation is required
for longer cable lengths. Active compensation can
occur on the receive side, camera side, or both. The
MAX7474 provides active compensation on the receive
side that is superior to balun, or active fixed cable
equalization.
Power Supply, Grounding, and Layout
The MAX7474 operates from a +4.75V to +5.25V single
supply. Connect both VCC inputs together and bypass
each one with a 0.1F capacitor to GND. Connect the
0.1F capacitors as close as possible to the device to
minimize the loop formed when the bypass capacitor is
connected to the device, thus avoiding additional
inductance that could resonate with the capacitor. For
optimum performance, use a ground plane and keep
the input and output traces away from each other.
