PIN FUNCTION DESCRIPTION
Equivalent Internal Circuit
Description
These pin provides a maximum of 26 dB attenuation
VCC
to vary the gain of each video amplifier separately.
5.0 V
50 k
Input voltage is from 0 to 5.0 V. Increasing the voltage
will increase the contrast level.

The input coupling capacitor is used for input
clamping storage. The maximum source impedance
is 100 Ω.
Input polarity of the video signal is positive.
Nominal 0.7 Vpp input signal is recommended
(maximum 1.0 Vpp).
Ground pin. Connect to a clean, solid ground.
These inputs are standard TTL level.

Connect to 8.0 Vdc supply, ±5%. Decoupling is
required at this pin.
On Screen Display contrast control.
Input voltage is from 0 to 5.0 V. Increasing the voltage
will increase the contrast of the OSD signal.
