11

Phase comparator

low-pass filter

(AM/FM switching)

VCC-1.0

The device operates in AM mode when a current of

over 200

µA flows from pin. 12.

Pilot detector low-

pass filter (Forced

mono) (VCO stop)

VCC-1.0

The device is forced to monaural when a current of

over 50

µA flows from this pin.

The VCO is stopped when a current of over 200

µA

flows from this pin.

The limit values for the resistor are the same as

those for pin 11.
