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
2VP-P into two source-terminated 75 loads (AC-coupled or
DC-coupled).
