Functional description
Equivalent circuit
20
S meter
Also functions as the
AM AGC
0.2 (FM)
0.9 (AM)
ILA00235
20
R
Internal load resistor R = 13.9 k
.
The SD response speed during seek
operations is set by the value of the
external capacitor connected to pin 20.
21
ILA00236
21
AM RF-IN
Vreg
Pin 21 and pin 22 (the AFC voltage) are
used at the same potential
ILA00237
22
AFC
Vreg
The FM SD bandwidth can be adjusted by
an external resistor connected between
pin 22 and pin 3 (the regulator voltage).
Note: A bandwidth of 180 kHz or higher is
appropriate for the FM SD bandwidth.
ILA00238
23
OSC
VCC
The oscillator coil is connected between
pin 23 and pin 9 (the VCC voltage).
Note: The oscillator coil impedance
(secondary side) must be at least
5 k
.
ILA00239
24
R
24
Oscillator buffer
Also functions as the
FM SD adjustment
VCC – 1.4
The FM SD sensitivity can be adjusted
with an external resistor on pin 24.
R = 200
Note: The resistance of the pin 24 external
resistor must be at least 3.3 k
.
