Description

The MSM75460 are single channel ADPCM CODEC ICs which perform mutual transcoding between an analog voice band signal 300 to 3400 Hz and 32 kbps ADPCM serial data.

Using advanced circuit technology, these MSM75460 operate using a single 5 V power supply and have low power consumption.

The MSM75460 are optimized for advanced digital cordless telephone system applications.
