Pin Definitions and Functions

Function

Pin No.

1, 2

Sym. Input for the AM signal in the frequency range of 100 kHz (SW) to 6.2

MHz (49m-Band) sym. application is recommended, asym. application is

possible

DC voltage alters the threshold voltage of the prestage AGC circuit.

GROUND: All DC values are referred to this pin

Buffered output for the by n divided (n = 8 or 10) oscillator frequency

Output for the internal reference voltage. This pin is to be blocked with a

ceramic capacitor to ground.

The ext. LC circuit between pin 7 and pin 8 determines the oscillator

frequency.

7, 8

Supply voltage. This point is to be blocked to ground for AF and for RF

signals.

Buffered output for the oscillator frequency

Input for the frequency divider. Low voltage to pin 11 divides the oscillator

frequency by 8, high voltage or open input divides by10.

Blocking capacitor for the IF AGC circuit to suppress AF frequencies

Input to select the fast or slow AGC time constant

Buffered AF output

Buffered output for the limited lower IF frequency. This signal is necessary

for an IF Counter Tuning System.

Buffered output for the AGC controlled lower IF signal. This pin is connected

to the AM stereo decoder.

Input pins for the DC coupled AGC amplifier

17, 18, 19

Open collector output of mixer for the lower IF (~ 450 MHz). A DC

connection to the tank circuit to V_refis recommended.

Sym. mixer 2 input for the upper IF (~ 10.7 MHz). Asym. operation is

possible. The input signal is converted to the lower IF corresponding the

21, 22

23, 24

equation f_LIF= f_UIF– f_2.LO

Input for the 2. local oscillator (LO). The pins can be connected via a quartz

or the oscillator is to be forced with an ext. signal.

Blocking capacitor for the prestage AGC

A capacitor to ground determines the AGC time constant. The DC potential

at this pin can be used for controlling the FET in the ext. prestage.

Sym. collector output of the mixer 1. The external tank circuit is tuned to the

upper IF.
