MegaQ™: An Automatic Composite Video Equalizer, Fully-Adaptive
to 1 Mile (1600m)
FN6739
Rev.3.00
May 22, 2019
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 75Ω loads (AC-coupled or
DC-coupled).

Pin Descriptions

PIN NAME
DESCRIPTION
INPUTS
3 IN+ High impedance analog input. This is the positive differential video input. Input signals are externally AC-coupled with
an external 1.0µF capacitor. See Applications Information section for information regarding input network for Cat x
and coax cables.
5 IN- High impedance analog input. This is the negative differential video input. Input signals are externally AC-coupled
with an external 1.0µF capacitor. See Applications Information section for information regarding input network for
Cat x and coax cables.
12 CFB Analog input. Bypass to ground with a 1500pF capacitor and connect to VIDEO OUT via a 0.047µF capacitor in series
with a 300resistor.
OUTPUTS
13
DIGITAL I/O
VIDEO OUT Single-ended video output. The internal AGC sets this level to 2VP-P for a nominal 1VP-P (pre-cable) video source.
7 EQ_DISABLE Digital Input. Equalizer Disable.
0: Normal Operation
1: Disables the equalizer to allow for insertion of upstream data onto the signal path, e.g. RS-485.
This pin must be asserted high or low. Do not float this pin.
8 COLOR Digital I/O. Color Indicator/Override.
0: Monochrome
1: Color
When used as an output, this pin indicates whether the incoming signal does or does not have a colorburst. When
used as an input, this pin forces the state machine to into monochrome or color mode. See Figure 49 and associated
text for more information on functionality.
When COLOR is not externally driven, it is an output pin with a 13k (typical) output impedance. It is capable of driving
5V, high-impedance CMOS logic.
Note: The COLOR indicator may be invalid for monochrome signals over greater than ~4800 feet. The device will still
equalize properly if this occurs.
9 INVERT Digital I/O. Polarity Indicator/Override.
0: Nominal Polarity.
1: Inverted Polarity.
When used as an output, this pin indicates the polarity of the incoming signal. When used as an input, this pin
controls whether or not the input signal is inverted in the signal chain. See Figure 48 and associated text for more
information on functionality.
When INVERT is not externally driven, it is an output pin with a 13k (typical) output impedance. It is capable of driving
5V, high-impedance CMOS logic.
In stand-alone mode, toggling this pin high-low-high or low-high-low will make the equalizer reacquire the signal.
10 LOCKED Digital Output.
0: Signal is not equalized (or not present).
1: Signal is equalized and settled.
Note: The LOCKED indicator may be invalid for monochrome signals over greater than ~4800 feet. The device will
still equalize properly if this occurs.
16 FREEZE Digital Input. Freezes equalizer in its current EQ state.
0: Continuous Update
1: Freeze EQ in current state.
For stand-alone operations, connect FREEZE to the LOCKED pin to enter the recommended Lock Until Reset mode.
Tie this pin low if unused.
SERIAL INTERFACE
18 SEN Digital Input. Serial Interface Enable. This pin should be tied to ground when not in use.
19 SCK Digital Input. Serial Interface Clock Signal. This pin should be tied to ground when not in use.
20 SD Digital I/O. Serial Interface Data Signal. This pin should be tied to ground when not in use.
POWER

VDD1
+5V power supply for analog equalizer. Isolate from +5V source with a ferrite bead and bypass to ground with a 0.1µF
capacitor in parallel with a 4.7µF capacitor.
