MegaQ™: An Automatic Composite Video Equalizer,
Fully-Adaptive to 1 Mile (1600m)
ISL59601, ISL59602, ISL59603, ISL59604, ISL59605
The ISL59601, ISL59602, ISL59603, ISL59604, and
ISL59605 (the “MegaQ™” product family) are single-channel
adaptive equalizers designed to automatically compensate for
long runs of Cat 5/6 or RG-59 cable, producing high quality
video output with no user interaction. The ISL59601 equalizes
Cat 5/6 up to a distance of 1000 feet (300 meters), while the
ISL59605 equalizes up to 5300 feet (1600 meters).
MegaQ™ compensates for high frequency cable losses of up to
60dB (ISL59605) at 5MHz as well as source amplitude
variations up to ±3dB.
The ISL59601, ISL59602, ISL59603, ISL59604, and
ISL59605 operate from a single +5V supply. Inputs are
AC-coupled and internally DC-restored. The output can drive
2V_P-P into two source-terminated 75Ω loads (AC-coupled or
DC-coupled).
