TA8132AN / AF , TA2012N / F 2002-10-30 7 Application Note 1. How to control the IF count output signal (pin(9) output) TUN LED ON OFF H Come out Non output L Non output Non output /Gb7/G20Whether or not there is the IF count output signal (pin(9) output) is determined by the and of the pin(8) control voltage: V 8 and tuning LED on / off switching. In the condition of V8: High (active high, VTH = 0.8V (typ.)) TUN LED: ON (Vin ≥ VL+2dBµV EMF (typ.)) the IF count output signal comes out from the pin(9). In the case of the tuning LED function is not needed, it doesn't matter the pin(10) is opened. /Gb7/G20The output impedance of pin(9) is 1.5kΩ (typ.) (cf.P .4) It is possible to reduce the IF count output signal level to add the resistance between the pin(9) and the VCC line. /Gb7/G20The signal waveform is the rectangular wave, and the level is 500mVp/G2dp (typ.) 2. How to control the divider of FM IF Switch V CC: 10.7MHz output GND or OPEN: 1.3375MHz output (1 / 8 dividing) 3. How to adjust the IF count output sensitivity /Gb7/G20The IF count output sensitivity (search sensitivity) Can be adjusted by varying the IF AMP gain for FM and varying the MIXER gain for AM. This setting is made by changing the value of external resistance R 2 which is connected to pin(2). /Gb7/G20However, this is only possible at the auto/G2dtuning mode. (external voltage supplied to pin(8) is at high level.) The original again returns while receiving a broadcast station (supplied voltage to pin(8) is at low level.)

When the R2 is over 10kΩ it is feared that the mode is change to the 1 / 8 IF mode. /Gb7/G20The gain loss of AM MIXER 0Ω 10K Ω /G2d16dB /G2d1dB 4. AM low/G2dcut circuit /Gb7/G20The AM low/G2dcut action is carried out by the bypass of the high frequency component of the positive/G2dfeedback signal at the AF AMP stage. The external capacitor: C by/G2dpasses this component. /Gb7/G20The cut/G2doff frequency fL is determine by the internal resistance 22kΩ (typ.) and the external capacitor C6 as following; (Hz) 6C310222 1 Lf /Gb4/Gb4/Gb4/G70/Gb4 /G3d /Gb7/G20In the case of the AM low/G2dcut function is not needed, set up the value of C6 over 0.47µF. In the condition of C6 ≥ 0.47µF, the frequency characteristic has flat response at the low frequency.
TA8132AN / AF , TA2012N / F 2002-10-30 9 5. AM local oscillator buffer output /Gb7/G20The output impedance of AM local oscillator buffer output pin (pin(4)) is 750Ω (typ.) (cf.P .3) /Gb7/G20It is possible to reduce the output level to add the resistance between the pin(4) and VCC line. The signal waveform is the rectangular wave, and the level is 500mVp/G2dp (fOSC = 1.45MHz, typ.) /Gb7/G20The higher local oscillation frequency (fOSC) to be, the lower buff output level to be owing to the load capacity. So, in the case that it is connected to other circuits, take care of the input capacity of these circuits and stray capacity of wire. 6. Tuning LED driver and stereo LED driver /Gb7/G20The tuning LED driver and stereo LED driver don't have current limit resistance shown in the right figure. So, it is necessary to add the current limit resistance: R 10, R11. /Gb7/G20Set up the values of R10, R11 to keep the drive currents ID10, ID11 under 10mA. 7.FM detection circuit For the FM detection circuit,detection coil is able to use instead of ceramic discriminator. Recommended circuit and recommended coil are as follows. In this case, please take care that V in (lim.) falls a little.

TA8132AN / AF , TA2012N / F 2002-10-30 10 8. FM / AM switch and forced monaural switch FM / AM switch over and stere / forced monaural switch over are done by internal PNP transistors ON / OFF which are connected to pin(16) and pin (17) respectively. The threshold voltages of these PNP transistors are V th = VCC, and for switching, we recommend to use mechanical switch. (Direct short to V CC line.) In the case of the electrical switch over by transistor, set up VCE (saturation voltage between collector and emitter) 50mV or less, otherwise there are some cases that it does not become the AM mode and force monaural mode. When these external switches are ON, the currents which flow into pin(16) and pin(17) are 100µA and 20µA respectively.
