Serial Register Interface ADPCM CODEC for Telephone Recording
GENERAL DESCRIPTION
The MSM7708-02 is a CMOS IC developed for applying to PHS (Personal Handyphone System).
This device provides a CODEC function which performs transcoding between the voice band
analog signal and 32 kbps ADPCM data. It also provides a serial register interface function for
telephone call recording.
Provided with such functions as DTMF tone and several kinds of tone generation, transmit/
receive data mute and gain control, side-tone pass, and voice/silence detection, the MSM7708-
02 is best suited for PHS handsets.
FEATURES
Single 3 V power supply operation (V
