Product Summary

The MT9075BP1 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. MT9075BP1 applications are: E1 add/drop multiplexers and channel banks, CO and PBX equipment interfaces, Primary Rate ISDN nodes, Digital Cross-connect Systems (DCS).

Parametrics

MT9075BP1 absolute maximum ratings: (1)Supply Voltage, VDD: -0.3 to 7 V; (2)Voltage at Digital Inputs, VI: -0.3 to VDD + 0.3 V; (3)Current at Digital Inputs, II: 30 mA; (4)Voltage at Digital Outputs, VO: -0.3 to VDD + 0.3 V; (5)Current at Digital Outputs, IO: 30 mA; (6)Storage Temperature, TST: -55 to 125 ℃.
