12 m pc2533 2.2 mix1 block fig. 2-2 mix1 block note output impedance and input impedance of buff1 are 330 w and 15 k w , respectively. mix1 (q101 to q108) is a dbm (double balanced mixer). mix1 output is supplied to 10.7 mhz ceramic filter via buff1 (output impedance: 330 w ) for impedance matching. the local oscillation signal is applied to the bases of q101 to q104, and the rf signal to the base of q105. mix1 (q101 to 108) multiplies the local oscillation signal by rf signal, and converts to the resonance frequency of ift t1 for output. the local oscillation signal is output from pin 1 via q109 (osc buff). it has an amplitude of 110 db m v and can be directly input to cmos lsi for use by the pll synthesizer. the rf signal applied to the base of q105 is also input to the detector of the rf agc circuit. 1 28 33 30 23 32 17 29 27 r11 q109 q105 v t t1 v cc r107 q106 q107 q108 r108 r109 r110 r111 r112 buff1 q104 q103 q102 q101 bias circuit to rf agc circuit (fig. 2-4) to 10.7 mhz bpf from lpf note + 31 osc1

16 m pc2533 2.6 if agc block fig. 2-6 if agc block (for m pc2533gs-01) if agc block configuration is shown in fig. 2-6. the signal detected from pin 15 is smoothed by the capacitor of pin 20, and its dc voltage controls the if agc. the if agc controls the if amplifier and mix2. in the operation sequence, it first controls the gain of the if amplifier, then controls the gain of mix2. the signal meter circuit output (current output) is in proportion to the dc voltage smoothed by pin 20, and converted to voltage by the external resistor of pin 7 or 9. therefore, output voltage value and gain can be set by the value of the external resistor. note note for relation between the external resistor and the signal meter, refer to signal meter output voltage (adjustment by resistor between pin 9 and gnd) in section 4. characteristic curves . bias circuit 7 20 9 q501 q503 q502 d501 q504 d502 r501 5 k w r502 5 k w v cc to mix2 (fig. 2-3) to if amp.

17 m pc2533 2.7 station detector circuit block fig. 2-7 station detector circuit block the configration station detector (sd) circuit block is shown in fig. 2-7. the sd circuit stops scanning or seeking when a broadcast wave is received when auto scanning or seek tuning. since the m pc2533 has two outputs (dc high/low signal (open collector) and ac if signal (f = 450 khz)), it can be used according to dts (digital tuning system) type. input the sd request signal from dts to pin 5. the sd sensitivity setting methods of the m pc2533gs-01 and m pc2533gs-02 differ. with the m pc2533gs-01, sd sensitivities in the if counter output system and in the high/low output system are set by external resistor between pin 7 and gnd and by external resistor between pin 9 and gnd. with the m pc2533gs-02, sd sensitivities in both the if counter output system and high/low output system are set by external resistor between pin 7 and gnd (refer to fig. 2-6). table 2-1 sd sensitivity setting examples value of resistor between pin 9 or pin 7 and gnd sd sensitivity (ac, dc) 51 k w 27 db m v 24 k w 29 db m v 10 k w 33 db m v bias circuit bias circuit + + + 10 5 6 8 1.0 v on/off 1.0 v detection comparator 1 detection comparator 2 from signal meter circuit (fig. 2-6) to time constant switchover circuit (fig. 2-6) from dts (request) sd output ( active hi g h ) sd ac output 450khz if input (from t3)
18 m pc2533 the reference voltage of the m pc2533-01 and m pc2533-02 detection comparator has been internally fixed at 1.0 v. under the influence of r501 (5 k w ) and r502 (5 k w ) of the siganl meter circuit (fig. 2-6), signal meter output voltage and detection comparator input voltage do not perfectly coincide. for sd sensitivity setting, refer to the following formula. detection comparator input voltage = signal meter output voltage (1 + r501 ) value of resistor between pin 7 and gnd remark because dc output is open-collector type (active high), connect pull-up resistor to pin 10 to use.
