Low voltage transmission circuits with
dialler interface
FM1062 / FM1062A
1.
GENERAL DESCRIPTION
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 / FM0162A improve the
EMC performance in-circuit which can enhance the telephone sets’ EMC.
2.
