Product Summary
The MT9075AP is an E1 Single Chip Transceiver. It integrates an advanced PCM 30 framer with a Line Interface Unit (LIU). The framer of the MT9075AP 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 applications of the MT9075AP include: E1 add/drop multiplexers and channel banks, CO and PBX equipment interfaces, Primary Rate ISDN nodes, Digital Cross-connect Systems (DCS).
Parametrics
MT9075AP 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 ℃.
Features
MT9075AP features: (1)Enhanced performance monitoring and programmable error insertion functions; (2)Low jitter DPLL for clock generation; (3)Operating under synchronized or free run mode; (4)Two-frame receive elastic buffer with controlled slip direction indication; (5)Selectable transmit or receive jitter attenuator; (6)Intel or Motorola non-multiplexed parallel microprocessor interface; (7)CRC-4 updating algorithm for intermediate path points of a message-based data link application; (8)ST-BUS/GCI 2.048 Mbit/s backplane bus for both data and signalling.
