    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.
