CPU: IC701
−
Forming/analyzing all data signals (ACK or CMD signal)
−
All interfaces (ex; LED, Key, Buzzer, Detector Circuit, Charge/Battery Low)
−
RAM for keeping the data (CH Number, ID Code, etc.)
•
RF IC: IC801
−
PLL Oscillator
−
Detection
−
Compress/Expander
−
1st/2nd mixer
−
Amplifier for transmission and reception
16.2. Reset Circuit
The power of handset is supplied by battery.
Whenever the battery is recharged or inserted, the impulse at CHG+ becomes Reset signal through Q704, and it is sent to CPU.
