MSM7540L/7560L
Single Rail ADPCM CODEC
GENERAL DESCRIPTION
The MSM7540L/7560L 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 from a single 3 V power supply and
provide low power consumption.
The MSM7540L/7560L are optimized for advanced digital cordless telephone system applications.
