Description

The MSM7570-01, developed for advanced digital cordless telephone systems, is a single channel ADPCM CODEC IC which performs mutual transcoding between the analog voice band signal and 32 kbps ADPCM serial data.

This MSM7570-01 includes 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 ciruit technology, the MSM7570-01 operates using a single 5 V power supply and have low power consumption.
