Description

The MT9075B is a single chip device which integrates an advanced PCM 30 framer with a Line Interface Unit (LIU). The framer interfaces to a 2.048 Mbit/s backplane and provides selectable rate data link access with

optional HDLC controllers for Sa bits and channel 16. The LIU interfaces the framer functions to the PCM

30 transformer-isolated four wire line.

Features

• Combined PCM 30 framer, Line Interface Unit (LIU) and link controllers in a 68 pin PLCC or 100 pin MQFP package

• Selectable bit rate data link access with optional Sa bits HDLC controller (HDLC0) and channel 16 HDLC controller (HDLC1)

• LIU dynamic range of 20 dB

• Enhanced performance monitoring and programmable error insertion functions

• Low jitter DPLL for clock generation

• Operating under synchronized or free run mode

• Two-frame receive elastic buffer with controlled slip direction indication

• Selectable transmit or receive jitter attenuator

• Intel or Motorola non-multiplexed parallel microprocessor interface

• CRC-4 updating algorithm for intermediate path points of a message-based data link application

• ST-BUS/GCI 2.048 Mbit/s backplane bus for both data and signalling

Applications

• E1 add/drop multiplexers and channel banks

• CO and PBX equipment interfaces

• Primary Rate ISDN nodes

• Digital Cross-connect Systems (DCS)
