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.
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.
Analog input. Bypass to ground with a 1500pF capacitor and connect to VIDEO OUT via a 0.022μF
capacitor in series with a 300Ω resistor.
(pre-cable) video source.
0: Normal Operation
1: Disables the equalizer to allow for insertion of upstream data onto the signal path, e.g. RS-485.
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.
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.
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.
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.
Digital Input. Serial Interface Enable.
Digital Input. Serial Interface Clock Signal.
Digital I/O. Serial Interface Data Signal.
