960MegaQ™: An Automatic 960H and Composite Video
Equalizer, Fully-Adaptive to 4000 Feet
ISL59960
The ISL59960 is a single-channel adaptive equalizer for 960H
(WD1) or 720H (D1) composite video designed to
automatically compensate for long runs of CAT 5/CAT 6 or
RG-59 cable, producing high quality video output with no user
interaction. The ISL59960 equalizes up to 4000 feet (1200
meters) of CAT 5/CAT 6 cable.
960MegaQ™ compensates for high frequency cable losses of
up to 70dB at 9MHz, as well as source amplitude variations up
to ±3dB.
The ISL59960 operates from a single +5V supply. Inputs are
AC-coupled and internally DC-restored. The output can drive
2VP-P into two source-terminated 75loads (AC-coupled or
DC-coupled).
