GENERAL DESCRIPTION
The PCD5032 is a CMOS device designed for use in
Digital Enhanced Cordless Telephone systems (DECT),
but also suitable for other cordless telephony applications
such as CT2. The PCD5032 performs analog-to-digital
and digital-to-analog conversion, ADPCM encoding and
decoding compliant to CCITT recommendation “G.721
(blue book, 1988)”. The PCD5032 contains on-chip
microphone and earpiece amplifiers. The device can be
used in both handset and base station designs.
