Microprocessor IEEE 1149.1 Interface Clock,Data Pulse Recovery Generator RM Loop Rx Equalizer & Data Slicer MT LoopMT9075B Data Sheet 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 S bits and channel 16. The LIU interfaces the framer functions to the PCM 30 transformer-isolated a four wire line. The MT9075B meets or supports the latest ITU-T Recommendations including G.703, G.704, G.706, G.732, G.775, G.796, G.823 for PCM 30, and I.431 for ISDN primary rate. It also meets or supports ETSI ETS 300 011, ETS 300 166 and ETS 300 233 as well as BS 6450. Change Summary Changes from the August 2005 issue to the August 2011 issue.
