ISO-CMOS ST-BUS FAMILY MT8950

Data Codec

ISSUE 4

November 1990

Features

Ordering Information

•

Transparent coding and decoding of 0 to 8, 9.6

and 19.2 kbps data

MT8950AC

24 Pin Ceramic DIP

0°C to 70°C

Coding compatible to PCM voice channels at

56/64 kbps in ST-BUS format

•

Automatic line polarity detection and correction

Loopback facility for test purposes

Description

Selectable data formats: RZ or NRZ

Eight user selectable modes of operation

Low power ISO-CMOS technology

The MT8950 is a coder/decoder which uses the

Transition Encoded Modulation (TEM) technique for

encoding/decoding low speed data to and from a 56/

64 kbps channel (equivalent to PCM Voice). The

coding and decoding scheme is transparent and can

accept either synchronous or asynchronous data up

to 8 kbps (inclusive); at 9.6 kbps and 19.2 kbps.

Applications

•

Transparent coder/decoder for synchronous

and asynchronous data

Data terminal (RS-232C, etc.) to ST-BUS

interface

The MT8950 is fabricated in MITEL’s ISO-CMOS

technology.

•

Data switching on digital PBXs
