Ref. No. Application/Function Operation/Condition/Compatibility

IC100 Power supply control IC Power supply control for BU5V. Composes stable power supply in combination with Q101. IC200 System microcomputer IC201 Reset IC Output Lo, when the voltage of the 5V microcomputer system goes at less than 4.2V. IC203 Buffer Reverse buffer for P-ON IN signal. IC400 Data decoder RDS data demodulation circuit. IC500 Serial communication RS422 serial communication driver and receiver. Q100 Voltage limiter Contains the BU voltage to 16V or less in combination with Q105. Q101 BU5V power supply Power supply output driver for BU 5V. Composes stable power supply in combination with IC100. Q103 5V 5V power supply. Q104 P ON SW When base becomes Hi, Q104 comes ON, supplying BU to 8V lines of the internal circuits. Q105 Voltage limiter Contains the BU voltage to 16V or less in combination with Q100.

Q106 BU detection SW

Q107 P ON SW When base becomes Hi, Q104 comes ON, supplying BU to 5V lines of the internal circuits. Q108,109,112 Q300 AMP RF input amplifier. Q301 AMP RF divide output signal amplifier. Q302 AMP F/E RF input signal amplifier.

8V power supply 8V Power Supply.

This is turned ON when BU comes ON. When momentary reduction is detected, or when BU is OFF, goes OFF.
