Multi-Function PCM CODEC

GENERAL 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 consists of analog speech path, key-scanner, tone generators,

CODEC meeting the m/A companding law, and processor interface, which are controlled via 8-

bit data buses.
