LOW VOLTAGE TRANSMISSION CIRCUITS
WITH DIALLER INTERFACE
SC1062/SC1062A
GENERAL DESCRIPTION
Outline Drawing
The SC1062/SC1062A are
integrated circuits that perform all
speech and line interface functions
required in fully electronic telephone
sets. They perform electronic switching
between dialing and speech. The ICs
operate at line voltage down to 1.6V DC
(with reduced performance) to facilitate
the use of more telephone sets connected
in parallel.
All statements and values refer to all versions unless otherwise specified.
F E AT U R E S
z Low DC line voltage: operates down to 1.6V (excluding polarity guard)
z Voltage regulator with adjustable static resistance
z Provides a supply for external circuits
z Symmetrical high-impedance inputs (64kΩ) for dynamic, magnetic or
piezoelectric microphones
z Asymmetrical high-impedance input (32kΩ) for electret microphones
z DTMF signal input with confidence tone
z Mute input for pulse or DTMF dialing
- SC1062: active HIGH (MUTE)
- SC1062A: active LOW (MUTE)
z Receiving amplifier for dynamic, magnetic or piezoelectric earpieces
z Large gain setting ranges on microphone and earpiece amplifiers
z Line loss compensation (line current dependent) for microphone and earpiece
amplifiers
z Gain control curve adaptable to exchange supply
z DC line voltage adjustment facility
