960MegaQ™: An Automatic 960H and Composite Video
Equalizer, Fully-Adaptive to 4000 Feet
ISL59960
Features
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.
• Equalizes both 960H and 720H video
• Equalizes up to 4000 feet of Cat 5/Cat 6 and up to 5000
feet (1500m) of RG-59
• Fully automatic, stand-alone operation - no user adjustment
required
• 13MHz -3dB bandwidth
960MegaQ™ compensates for high frequency cable losses of
up to 70dB at 9MHz, as well as source amplitude variations up
to ±3dB.
• ±8kV ESD protection on all inputs
• Automatic cable type compensation
The ISL59960 operates from a single +5V supply. Inputs are
AC-coupled and internally DC-restored. The output can drive
• Compatible with color or monochrome, 960H, NTSC or PAL
signals
2V
into two source-terminated 75Ω loads (AC-coupled or
P-P
• Automatic polarity detection and inversion
DC-coupled).
• Compensates for ±3dB source variation (in addition to cable
losses)
