Description
O
FM demodulator output pin. Output signal frequency is within
the audio band.
I
Normally provides a 455kHz carry frequency for the FM quadra-
ture detector.
O
IF amplifier output pin. Signal will later pass through external
90°C phase shifter for quadrature detector.
¾ Analog ground
¾ Normally connected to VCC1 through a capacitor.
I
IF amplifier input pin it is necessary to use the IF filter network
to get high quality IF signal.
¾ Analog power supply
O
Second mixer IF signal output pin and down converter. IF fre-
quency is 455kHz.
¾ Connect to ground through capacitor.
I
Second mixer RF signal input pin and down converter. Fre-
quency is 455kHz.
¾ Expander rectifier filter capacitor pin.
O
First mixer IF signal output pin and down converter. IF fre-
quency is 10.7MHz.
O Reference voltage input for compander.
I
The first mixer RF signal input. Carrier frequency from
20~60MHz.
¾ Directly connects to the two voltage regulators inside.
I Normally connected to ground through a capacitor.
I
Connects LC network with VCO2 pin to provide the tank circuit
for the received voltage control oscillator.
