MSM7540/7560
Single Rail ADPCM CODEC
GENERAL DESCRIPTION
The MSM7540/7560 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 devices operate using a single 5 V power supply and
have low power consumption.
The MSM7540/7560 are optimized for advanced digital cordless telephone system applications.
