Additional preview pages of the MSM7708-02 datasheet.

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.

Single 3 V power supply operation (VDD: 2.7 V to 3.6 V).
Low power consumption When system is operating: 6 mA typ. When powered down: 0.02 mA typ. (ADPCM CODEC).
ADPCM: ITU-T Recommendations G.721 (32 kbps).
Transmit/receive full duplex capability.
PCM interface code format: m-law or A-law selectable.
Serial ADPCM and PCM transmission rate: 64 kbps to 2,048 kbps.
Transmit/receive mute function; transmit/receive programmable gain set.
