DESCRIPTION
A test pin. Set open or to L level in the normal mode.
A test pin. Set open or to L level in the normal mode.
An input pin for resetting internal vertical counter.
The input pulse is VSYNC. (negative polarity)
An input pin to select TV standards.
L level
: EIA mode
H level or open : CCIR mode
An output pin of composite synchronous signal pulse.
Supply of +5 V power.
A grounding pin.
An output pin of composite blanking pulse.
The pulse occurs at the start of every line.
The pulse occurs at the start of every field.
A pulse that corresponds to the cease period of the
horizontal transfer pulse.
A test pin. Set open or to L level in the normal mode.
A pulse to clamp the optical black signal. This pulse
stays low during the absence of effective pixels within
the vertical blanking.
A test pin. Set open or to L level in the normal mode.
A test pin. Set open or to L level in the normal mode.
A grounding pin.
An input pin for resetting all internal circuits at power on.
Connect VDD through the diode and through the
capacitor.
Supply of +5 V power.
An input pin to control electronic exposure mode, flicker-
less mode and WIND (pin 39) pulse output.
