048 Mbit/s backplane bus for both data and signalling ISSUE 1 March 1998 • Ordering Information MT9075BP 68Pin PLCC MT9075BL 100 Pin MQFP -40°C to 85°C • • • • • • • • • 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.
The MT9075B meets or supports the latest ITU-T Recommendations including G.
