MT9172 - DSIC

Download the MT9172 datasheet PDF. This datasheet also covers the MT9171 variant, as both devices belong to the same dsic family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
