PIN FUNCTION DESCRIPTION

Symbol

Internal Equivalent Circuit

Description/External Circuit Requirements

IF Amplifier Input

Pin 4 is the IF input pin. The typical input impedance

at this pin is 10 k. The input should be ac coupled

through a 0.01 µF capacitor.

10 k

Gnd

Supply Ground

In the PCB layout, the ground pin should be

connected to the chassis ground directly. This pin

is the internal circuit ground and the silicon

substrate ground.

IND

Stereo Indicator Driver

This driver circuit is intended to light an LED or

other indicator when the decoder receives the

proper input signals and switches into the stereo

mode. The maximum amount of current that the

circuit can sink is 10 mA.

A current limiting resistor is applied externally to

control LED brightness versus total power supply

current.

30 k

Regulated Voltage, 1.0 V

Ref

An electrolytic capacitor used as a bypass filter is

recommended from Pin 7 to ground. The capacitor

value should be 10 µF.

Blend Cap

Charging

Circuit

The value of the capacitor on this pin will effect the

time constant of the decoder blend function. The

recommended value is 10 µF from Pin 8 to ground.

The dc level at Pin 8 is internally generated in

response to input signal level and signal quality. This

pin is a key indicator of the operational state of the IC

(see text Functional Description). It is recommended

to discharge the blend capacitor externally when

changing stations.

Pilot I Detector Output

Pilot

The Pilot I Detector output requires a 10 µF

electrolytic capacitor to ground. The value of this

capacitor sets the pilot acquisition time. The dc

level at Pin 9 is approximately 1.0 Vdc, unlocked,

and 1.1 to 2.4 Vdc in the locked condition.
