Power switch It is necessary to connect an external pull-down resistor with the terminal of PW SW (pin), in case that this IC is turned on due to external noise etc. 2. Mode switch The terminal of AM/FM changeover is pind. In controlling the AM/FM mode with voltage, it is applied as follows. ( Vcc : AM mode OPEN: FM mode ln FM mode, care should be taken to eliminate influence due to external noise etc, because this terminal is opened. The leak current flows through this terminal, in the case that the terminal is connected to Vcc line independently, even through this IC is off mode (the terminal of PW SW (pin) is off mode). 3. IF count output IF count signal can be taken from IF output terminal (pin@), when IF request terminal (pind) is connected with GND through Rs_en and stop pulse sensitivity is on.

FM stop pulse sensitivity FM stop pulse sensitivity can be changed by connecting an external resistor RseEN between IF request terminal (pind) and GND. The gain of FM IF amplifier is controlled by Rsen, and FM stop pulse sensitivity is changed. It is advised that Rsey is 100kQ or less.

MPX IN This IC can attenuate only FM stereo main signal level. Because MPX input for main signal (pin@) is independent of that for pilot signal (pin@), this terminal is shared with AM input). Internal circuit of MPX IN terminal (pin@) is shown in Fig.2. FM stereo main signal level can be attenuated by connecting an external resistor Ry. Because FM stereo main signal level is attenuated by internal resistor (14kQ. and 10kQ) and resistor Rx. And it is applied to an emitter of transistor Q. Fig.2 Internal circuit of MPX 6. AM tweets IN terminal It is necessary to connect the capacitor Ct (about 330pF) DET Vee OUT between Vcc terminal (pin) and DET OUT (pin@), in case that AM tweets occurs by pattern layout. (Fig.3) This Ct can also functions as phase compensation of MPX stage. 330pF 7. AM AGC Fig.3 Countermeasures for AM It is necessary to connect a capacitor C (about 68pF) between tweets Vcc terminal (pin) and AM IF IN terminal (pin@), in case that AGC circuit doesnt operate normally. Because second harmonic of local oscillator is applied AM IF terminal (pin@) by pattern 6 iN layout. c In case that capacitor (C=68pF) is connected, AM stop pulse q sensitivity is delayed about 1dB. 7 Output DC voltage of AGC terminal (pin) is Vg =0.1V (Typ., Fig.4 AM trap circuit AM mode, at no signal). 8. Stereo indicator/AM IF output (for AM stereo) @ The terminal of pin is built in stereo indicator function and modulated AM IF signal output. In AM mode, Rip (3kQ or less) should be connected between Vcc and pin, or pin should connected to Vcc directly. (Fig.5) In case that Rip >3kQ or pin is opened, this IC doesn't operate normally in AM mode. Because transistor Q2 is saturated.
