Pin Functions
Pin No.
Function
1, 2
Demodulator tank circuit connection IF 1
(high impedance input – slope of S-curve can be determined by external resistor
between pins 1 and 2)
3
GND
4
AF output IF 1 (emitter follower)
5
AF output IF 2 (emitter follower)
6
Supply voltage
7, 8
Demodulator tank circuit connection IF 2
(high impedance input – slope of S-curve can be determined by external resistor
between pins 1 and 2)
9
Operating point feedback of limiter amplifier and low end IF 2
(RF decoupling of IF amplifiers with appropriate capacitors is required!
11
IF 2 input
(input of limiter amplifier IF 2; internal resistor between pins 9 and 11 is typ. 800
)
12
GND
13
Internal reference voltage (typ. 6 V)
14
IF 1 input
(input of limiter amplifier IF 2; internal resistor between pins 14 and 15 is
typ. 800
)
15
Operating feedback of limiter amplifier IF 1
(RF decoupling of IF amplifiers with appropriate capacitors is required!)
16
Operating point feedback of limiter amplifier and low end IF 1
(RF decoupling of IF amplifiers with appropriate capacitors is required!)
10
Operating point feedback of limiter amplifier IF 2
(RF decoupling of IF amplifiers with appropriate capacitors is required!)
