Description
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.
The MT8950 is fabricated in MITEL’s ISO-CMOS technology.

Features
• Transparent coding and decoding of 0 to 8, 9.6 and 19.2 kbps data
• 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
• Selectable data formats: RZ or NRZ
• Eight user selectable modes of operation
• Low power ISO-CMOS technology

Applications
• Transparent coder/decoder for synchronous and asynchronous data
• Data terminal (RS-232C, etc.) to ST-BUS interface
• Data switching on digital PBXs
• Channel banks/TDM multiplexers
