Functional description

Phase comparator

filter connection

11

Also functions as the

FM/AM switching

input

VCC – 1.0

The IC switches to AM mode if a current in

excess of 200 µA flows from this pin

Pilot detector filter

connection

12

Also functions as the

forced mono setting

Also functions as the

VCO stop control

VCC – 1.0

The IC switches to forced mono mode if a

current in excess of 50 µA flows from this

pin.

The VCO circuit is stopped if a current in

excess of 200 µA flows from this pin.
