Proper Cares in Using the IC
External parts placement and pattern
The AM local oscillation parts, AM local oscillation coil, and antenna circuit parts such as bar antenna must be
separated from each other as far as possible to prevent Qs from worsening.
Pin 16 (AM oscillation injection pin) and pin 14 (RF input pin) must be separated from each other on the pattern as
shown in Figure. A below. Care should be taken not to make unwanted coupling by parallel wiring as shown in
Figure B to prevent Qs from worsening.
FM quadrature detection coil
The values recommended for the detection coil are shown below. (See Figure 1.)
Tuning capacitance : 56pF
Damping resistance : 6.8k
Ω
Values other than recommended provide the LED drive characteristic as shown below.
Figure A Good example
Figure B Bad example

Tuning capacitance
Lighting is delayed.
No lighting may occur at low
temperature.
Lighting is advanced.
Mislighting may occur in the
absence of signal.
Damping resistance
Lighting is advanced.
Mislighting may occur in the
absence of signal.
Lighting is delayed.
No lighting may occur at low
temperature.
If the product of tuning capacitance and damping resistance is equal to that of values recommended above (e. g.
tuning capacitance=82pF, damping resistance=4.7k
Ω), other characteristics (demodulation output, S/N, THD, etc.)
than the LED drive characteristic remain almost unaffected.
For applications where a double tuning coil is used, refer to "Applications where a double coil is used" on page 13.
