Overview
® CMOS ST-BUS™ FAMILY MT8910-1 Digital Subscriber Line Interface Circuit Preliminary Information Features • • • • • • • • • • • • Compatible with ISDN U-Interface standard Over 40dB ( @ 40 kHz) of loop attenuation Full duplex transmission over single twisted pair Advanced echo cancelling technology High performance 2B1Q line code Full activation/deactivation state machine QSNR and line attenuation diagnostics Frame and superframe synchronization On-chip 15 second timer Insertion loss measurement test signal & quiet mode Mitel ST-BUS compatible Single 5V power supply ISSUE 1 August 1993 Ordering Information MT8910-1AC 28 Pin Ceramic DIP MT8910-1AP 44 Pin PLCC 0°C to +70°C Description The MT8910-1 Digital Subscriber Line Interface Circuit (DSLIC) is designed to provide ISDN basic rate access (2B+D) at the U-interface.
Full duplex digital transmission at 160 kbit/s on a single twisted pair is achieved using echo cancelling hybrid (ECH) technology.
This, in conjunction with the high performance 2B1Q line code, allows the DSLIC to meet the loop length requirements of the digital subscriber loops at the U-interface over the entire non-loaded telephone loop plant.
The MT8910-1 is compatible with the complete range of Mitel Semiconductor ISDN components through the use of the ST-BUS interface.
Applications • • • • ISDN NT1 and NT2 DSL interface Digital PABX line cards and telephone sets Digital multiplexers and concentrators Pair gain system DSTi CDSTi Transmit Interface Scrambler & Encoder DAC and Tx Filter + Lout+ MRST F0b C4b SFb F0od MS0 MS1 NT/LT Control Register Jitter Compensator Linear Echo Canceller NonLinear Compensator - Lout- Tone Detector TRANSMIT/ RECEIVE TIMING & CONTROL INTERFACE Framing & Maintenance Decision Feedback Equalizer 2nd Order PDM ADC Status Register Quantizer FIR Digital Filter CDSTo DSTo Receive Interface Descrambler, Decoder & Diagnostics Timing Adaptation Circuit Bias & Voltage Ref.
