Proper Cares in Using the ICExternal 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 : 6.8kΩ• Values other than recommended provide the LED drive characteristic as shown below.

Figure A Good example Figure B Bad example

Value increased Value decreased

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=4.7kΩ), 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.

How to apply FM AFC

The S curve at the FM output pin (pin 8) is as shown in Figure 1. Therefore, the domestic (Japan) band (lower local

oscillation) use and foreign band (upper local oscillation) use differ as shown in Figures 2 and 3.

AM local oscillation

Since the LA1260 contains an ALC circuit, the oscillation level at pin 16 can be limited to 60 to 150mV in the

following applications where a coil is used.

Stable oscillation occurs at a coil impedance of 5kΩ or greater viewed from across pins 16 and 15. Turn ratio n and

QO must be determined so that the oscillation level at pin 16 becomes 75mV or greater for MW use and 60mV or

greater for SW use.

If turn ratio n is increased more than needed, the oscillation level at pin 16

drops, thereby lowering the maximum sensitivity as shown in Figure 5 and 6.

Figure 7 shows the relation between turn ratio n and oscillation level at pin

16 in the MW band.

AM oscillation coil

Generally speaking, the following should be noted. Winding with loose

coupling between 1 and 2 and between 1 and 3 must be avoided. (Particularly

SW1, SW2).

To put in concretely, the pot core type is better than the screw core type which

is loose in coupling. This prevents the local oscillation frequency from turning

third resonance frequency related to the coupling coefficient.

LED unlighted time and distortion in AM (MW)

By increasing the value of the electrolytic capacitor for AGC at pin 11 (Figure 8), the distortion in the AM mode can

be improved, but the LED unlighted time is made longer. 10µF is recommended for obtaining the optimum LED

unlighted time and distortion. The LED unlighted time is 200ms at this value (Approximately 400ms at 22µF).

FM-AM selection and dc level at pin 12

(1) Pin 12-used method=recommended circuit

The FM mode is entered with pin 12 open. When pin 12 and pin 6

are at the same potential in terms of DC, the AM circuit is turned on

by the internal switch. It should be noted that the dynamic range is

narrowed whether the potential at pin 12 is lower or high than that

at pin 6.

(2) Pin 13-used method

The AM mode is entered with pin 13 open. When pin 13 is

grounded, the FM circuit is turned on and the AM circuit is turned

off by the internal switch. In this case, pin 12 and pin 6 (VCC) are

at the same potential.
