Function

Phase comparator output.

Power supply for VCO.

Reference for VCO. Generally connected to GND(D) through an external resistor.

VCO controlled voltage input. Generally connected to PCO through an external loop filter.

GND for D/A converter.

Luminance signal output.

Power supply for D/A converter.

Chrominance signal output.

Reference for D/A converter. Generally connected to GND(DA) through a multi–layer ceramic capacitor

(0.1 µF).

Bias circuit current control for A/D, D/A converters. Generally connected to GND(DA) through an external

resistor.

GND for A/D converter.

Power supply for A/D converter.

Top reference for A/D converter. Supplies top reference voltage internally.

Bottom reference for A/D converter. Supplies bottom reference voltage internally.

A/D converter input.

Voltage output for clamp. Clamps an input signal by connecting with Vin and inputs the video signal by ac

coupling.

Clamp time constant setting pin.

No connection.

GND for digital circuit.

CLK input for A/D converter. Available only during digital input comb filter mode and a portion of test

mode. Input level is CMOS level.

Mode inputs. GND level during normal (FSC) mode.

Test mode inputs. Generally GND level.

Vertical enhancer level at normal mode. Generally VCC(D) level.

Vertical enhancer level at normal mode. Generally GND(D) level.

Vertical enhancer level at normal mode. Generally VCC(D) level.

Vertical enhancer level at normal mode. Generally VCC(D) level.

Vertical enhancer level at normal mode. Generally GND(D) level.

NC pin at normal mode. Generally GND(D) level.

Non–YC separation processing mode. Generally GND(D) level.

Vertical enhancer circuit mode. Generally GND(D) level.

GND for digital circuit.

Power supply for digital circuit.

CLK input. ac coupling input by external capacitor. Normal (FSC) mode: Subcarrier. Normal (4xFSC)

mode: 4*Subcarrier.

PAL N/PAL M setting pin. Generally GND level.

PAL/NTSC setting pin. Generally GND level (PAL mode).

Comb/BPF setting pin. Generally GND level (comb filter mode).
