Multi-Function ADPCM CODEC
GENERAL 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 device 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 device operates using a single 5 V power supply and have
low power consumption.
