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 identica...
