Overview
ISO2-CMOS ST-BUS FAMILY MT9171/72 Digital Subscriber Interface Circuit Digital Network Interface Circuit Data Sheet Features • Full-duplex transmission over a single twisted pair • Selectable 80 or 160 kbit/s line rate • Adaptive echo cancellation • Up to 3 km (9171) and 4 km (9172) • Integrated services digital network (ISDN) compatible (2B+D) data format • Transparent modem capability • Frame synchronization and clock extraction • Microsemi® ST-BUS compatible • Low power (typically 50 mW), single 5 V supply Applications • Digital subscriber lines • High speed data transmission over twisted wires • Digital PABX line cards and telephone sets • 80 or 160 kbit/s single chip modem March 2013 Ordering Information MT9171/72AP1 MT9171/72AN1 MT9171/72APR1 MT9171/72ANR1 28 Pin PLCC* 24 Pin SSOP* 28 Pin PLCC* 24 Pin SSOP* *Pb Free Matte Tin -40C to +85C Tubes Tubes Tape & Reel Tape & Reel Description The MT9171 (DSIC) and MT9172 (DNIC) are pins for pin compatible replacements for the MT8971 and MT8972, respectively.
They are multi-functional devices capable of providing high speed, full-duplex digital transmission up to 160 kbit/s over a twisted wire pair.
They use adaptive echo-cancelling techniques and transfer data in (2B+D) format compatible to the ISDN basic rate.
Several modes of operation allow an easy interface to digital telecommunication networks including use as a high speed limited distance modem with data rates up to 160 kbit/s.
Both devices function identically but with the DSIC having a shorter maximum loop reach specification.
The generic "DNIC" is used to reference both devices unless otherwise noted.
The MT9171/72 is fabricated in Microsemi ISO2-CMOS process.
