Equivalent circuit
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.
Limit values for the resistor :
2.7k
Ω (When VCC = 7V)
3.9k
Ω (8V)

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.
