Pins 14, 15 and 16

Pins 14, 15 and 16 are the APL level reference voltage pins.

When the APL filter pin (pin 8) voltage is higher than the pin 14 reference voltage (2.6 V), the APL level is judged to be

high. If that voltage is lower than the pin 15 reference voltage, the APL level is judged to be low. Pin 16 is a reference

voltage for the high-frequency detection circuit, and the vertical line saturation suppression circuit operates when the pin

8 voltage is lower than the pin 16 voltage. See the description of the APL filter voltage characteristics on page 10 for

details on the relationship between the APL level and the APL filter pin voltage.

Pin 17

Pin 17 mutes the correction circuit.

Pin 18

Pin 18 is the 2.0 V Y signal system reference voltage pin.

This reference voltage pin determines the Y signal system clamp and output voltages. C1 is used to exclude noise from

the reference voltage line.
