Description
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.

Red Video In
Power supply pin (excluding output stage)
Video inputs. These inputs must be AC
Coupled with a minimum of a 1 μF cap, 10
μF is preferred. A series resistor of about
33
must be used for ESD protection.

Red Clamp Cap
The external clamp cap is charged and
discharged to the correction voltage
needed for DC restoration. 0.1 μF is the
recommended value.

Ground
Contrast
Ground pin.
Contrast control pin:
4V - no attenuation
0V - over 40 dB attenuation
Drive control pins:
4V - no attenuation
0V - 20 dB attenuation

Sandcastle Input
The sandcastle input allows for blanking
only, or blanking with DC restoration.
Blanking requires a 2V input. Clamping
with blanking requires a 4V input.

Blue Video Out
Video output. For proper black level the
output must drive 390
impedance.
