will go high. However once lock is achieved, noise and
average-picture-level changes may cause the device to
unlock, causing some image perturbation while MegaQ
re-equalizes.
The Continuous Update mode is enabled whenever the
FREEZE pin is set to a logic low (grounded).
Polarity Detection and Correction
MegaQ features polarity detection and correction,
automatically detecting incorrectly-wired input signals
and inverting the signal inside the IC as necessary. The
detected polarity is indicated by the state of the INVERT
pin.
The INVERT pin has 2 modes of operation. It is typically
used to indicate whether or not the incoming signal is
inverted (the “+” signal on the “-” input and vice-versa).
The state of the invert signal is then used to tell the
signal processing logic whether or not to invert the signal
in the signal path.
A logic high on INVERT indicates that the positive
differential input signal is on IN- (pin 5) and the negative
differential input signal is on IN+ (pin 3). A logic low
indicates nominal polarity.
However the unique design of the INVERT I/O pin
(Figure 48) also allows MegaQ’s internal inversion
detector to be overdriven externally, forcing MegaQ to
invert or not invert the signal regardless of the state of
the inversion detection function. This is not necessary in
normal operation, but it may improve performance in
particularly noisy environments when the polarity of the
signal is guaranteed to be correct.
The COLOR Pin
The color pin has 2 modes of operation. It is typically
used to indicate whether or not the incoming signal has a
colorburst or not. The state of the color signal is then
used to tell the signal processing logic whether or not it
can rely on the presence of a colorburst signal. A logic
high indicates a color signal; a logic low indicates
monochrome.
However the unique design of the COLOR I/O pin
(Figure 49) also allows MegaQ’s internal color detector
to be overdriven externally. This is not necessary in
normal operation, but it may improve performance in
particularly noisy environments when the signal type is
predetermined.
Monochrome Video Signals
MegaQ will equalize monochrome signals to the same
distance as color signals. However due to the high level
of noise past ~4800 feet, above ~4800 feet the COLOR
and LOCKED indicators may become invalid for
monochrome signals. The device will still equalize
properly if this occurs.
Security Cameras
MegaQ is ideal for security camera installations.
The automatic adaptive equalizer doesn't need any active
silicon on the transmit side of the cable, enabling
upgrading of older installations without having to touch
the installed camera base, including older monochrome
cameras.
MegaQ automatically adjusts for wiring polarity errors
as well as adjusts for optimum image quality. These
features eliminates the need for the installer to make any
adjustments.
With an extended equalization range of 5300ft, the
ISL59605 enables cameras to be placed in even more
remote locations, enabling coverage of up to three
square miles from a single monitoring station.
