GENERAL DESCRIPTION
The MSM7570L-01/02, developed for advanced digital cordless telephone systems, are single channel ADPCM CODEC ICs which perform mutual transcoding between the analog voice band signal and 32 kbps ADPCM serial data.
The devices include DTMF Tone and several types of tone generation, transmit/receive data mute and gain control, side-tone path and gain control, and VOX function. Using advanced circuit technology, these devices operate from a single 3 V power supply and provide low power consumption.
