Universal Telephone IC
All Functions Integrated
Description
TEMIC’s low-voltage telephone circuit U3762MB
performs all the speech and line interface functions
required in an electronic telephone set, the tone ringer, the
pulse and DTMF dialing with redial. Operation below
15 mA is possible with reduced performance (no dialing).
Features
Speech Circuit
Adjustable DC characteristic
Symmetrical input of microphone amplifier
Receiving amplifier for dynamic or
piezo-electric earpieces
Automatic line-loss compensation
Anti-clipping in transmit direction
Dialer
DTMF / pulse switchable
Pulse dialing 66/33 or 60/40 or DTMF dialing
selectable by pin
Flashing time duration 98 ms
Pause function
Last number redial up to 32 digits
Standard low-cost crystal 3.57 MHz or
ceramic resonator
Key tone
Tone Ringer
2-tone ringer
Adjustable volume
RC oscillator
Adjustable threshold
Benefits
Low number of external components
High quality through one IC solution
