Overview
ICM7101D is a single chip telephone CMOS
integrated circuits that meets multiple PTT
requirements, allowing phone manufacturers
to have single board design for various
countries. This reduces inventory and simplify
manufacturing processes.
ICM7101D integrates dialer, speech, and
ringer circuits. The integration reduces
component counts, hence increases product
reliability.
