Product Summary

The MSM7732-01LAZ060 is a single-channel full duplex CODEC CMOS IC which performs mutual transcoding between the analog voice band signals and 64 kbps PCM serial data. The MSM7732-01LAZ060 performs such functions as DTMF tone and several types of tone generation, transmit/receive data mute and gain control, and side tone path.
