MSM7590L-01
Multi-Function ADPCM CODEC
GENERAL DESCRIPTION
The MSM7590L-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 circuit technology, the device operates from a single 3 V power supply and
provide low power consumption.
