Description

The MSM7732 is a single-channel full duplex CODEC LSI device which performs mutual transcoding between analog voice band signals ranging from 300 to 3400 Hz and the 64 kbps PCM serial data.

Provided with such functions as DTMF Tone generation, transmit/receive data gain control,and side-tone path, the MSM7732 is best suited for telephone terminals in digital wireless systems.
