Pin No.
Function
Description
Equivalent circuit
Continued from preceding page.
Continued on next page.
The HCC frequency characteristics
41
HCC capacitor
are determined by the external
capacitor connected at this pin.
This pin is used to change the
frequency characteristics of the
unneeded audio band under
100 Hz in AM mode to produce
a clear audio signal.
Note: The LC capacitor must be
connected between this pin
and VCC (pin 40).
42
AM L.C. pin
This is because the detector
circuit operates referenced
to VCC.
The cutoff frequency fC is
determined by the following
formula.
fC = 1/2π× 50 k × C
Inserting a 1-M
resistor between
43
Pilot detector
pin 43 and VCC will force the IC
to mono mode.
