Product Overview
Instruction
The FM1062 and FM1062A are integrated circuits that perform all speech and line interface
functions required in fully electronic telephone sets. They perform electronic switching between
dialling and speech. The ICs operate at line voltage down to 1.6 V DC (with reduced performance)
to facilitate the use of more telephone sets connected in parallel. FM1062 / FM1062A improve the
EMC performance in-circuit which can enhance the telephone sets’ EMC.
Features
‹ Low DC line voltage; operates down to 1.6 V (excluding polarity guard)
‹ Voltage regulator with adjustable static resistance
‹ Provides a supply for external circuits
‹ Symmetrical high-impedance inputs (64K) for dynamic, magnetic or piezoelectric
microphones
‹ Asymmetrical high-impedance input (32K) for electrets microphones
‹ DTMF signal input with confidence tone
‹ Mute input for pulse or DTMF dialling
FM1062: active HIGH (MUTE)
FM1062A: active LOW (MUTE)
‹ Receiving amplifier for dynamic, magnetic or piezoelectric earpieces
‹ Large gain setting ranges on microphone and earpiece amplifiers
‹ Line loss compensation (line current dependent) for microphone and earpiece
amplifiers
‹ Gain control curve adaptable to exchange supply
‹ DC line voltage adjustment facility
‹ enhanced EMC performance
