Description

The MSM7575, developed for advanced digital cordless telephone systems, is a single channel full duplex CODEC which performs mutual transcoding between the analog voice band signal and the 64 kbps PCM serial data.

This MSM7575 performs DTMF tone and several kinds of tone generation, transmit/receive data mute and gain control, side-tone pass and its gain control, and VOX function.

Using advanced circuit technology, this MSM7575 operates from a single 3 V power supply and provides low power consumption.
