Description
1
Red OSD Input
These are standard TTL inputs. An OSD
signal at any of the three pins will
automatically switch the pre-amp into the
OSD mode. 7 colors, including white, are
available.
19
Blue OSD Input
20
Green OSD Input
2V
CC1
Power supply pin (excluding output stage)
3
Red Video In
Video inputs. These inputs
must be AC
Coupled with a minimum ofa1F cap, 10
F is preferred. A series resistor of about
33
must be used for ESD protection.
5
Green Video In
8
Blue Video In
4
Red Clamp Cap
The external clamp cap is charged and
discharged to the correction voltage
needed for DC restoration. 0.1 F is the
recommended value.
7
Green Clamp Cap
9
Blue Clamp Cap
6
Ground
Ground pin.
10
Contrast
Contrast control pin:
4V - no attenuation
0V - over 40 dB attenuation
Drive control pins:
4V - no attenuation
0V - 20 dB attenuation
12
Blue Drive
14
Green Drive
17
Red Drive
11
Clamp Pulse
The clamp pulse activates the DC
restoration circuitry. A 3.6V input is
required to activate the clamp pulse.
13
Blue Video Out
Video output. For proper black level the
output must drive 390
impedance.
