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.
FEATURES
•Single 3 V Power Supply Operation
•ADPCM Algorithm : Complies completely with 1988's version ITU-T G.721 (32
kbps)
•Transmit/Receive Full-Duplex Operation
• Transmit/Receive Synchronous Mode Only
•Serial ADPCM Transmission Data Rate : 32 kbps to 2048 kbps
• Serial PCM Transmission Data Rate : 64 kbps to 2048 kbps
• PCM Interface Coding Format
MSM7540L : A-law or Linear (14 bit, 2's compliment) Selectable
MSM7560L : m-law or Linear (14 bit, 2's compliment) Selectable
• Low Power Consumption
