MT9075BPR1

Telecom Overview

The MT9075BPR1 is a single-chip device integrating an advanced PCM 30 framer with a Line Interface Unit (LIU). It interfaces to a 2.048 Mbit/s backplane and provides selectable rate data link access with optional HDLC controllers for S a bits and channel 16. The LIU connects the framer functions to a transformer-isolated four-wire line. This component supports ITU-T Recommendations G.703, G.704, G.706, G.732, G.775, G.796, and G.823 for PCM 30, as well as I.431 for ISDN primary rate.
