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. MSM7708-02 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.
