Description

The MSM7503 is a high performance, low power CODEC LSI device integrating a 2-wire time division transmission (ping-pong transmission) interface function and has a basic function of man-machine interface to that of the MSM7502.

The MSM7503 operates from single 5 V power supply and is ideal for digital telephone terminals such as pushbutton telephone sets and digital PBXs.

The MSM7503 ping-pong transmission interface supports a bidirectional communication of up to 800 m long on the 2-wire twisted pair line, and can send and receive voice data at 64 kbps and control data at 16 kbps.

The man-machine interface of MSM7503 consists of analog speech path, key-scanner, tone generators,CODEC meeting the /A companding law, and processor interface, which are controlled via 8-bit data buses.
