MT9171 - Digital Network Interface Circuit

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

General Description

The MT9171 (DSIC) and MT9172 (DNIC) are pin for pin compatible replacements for the MT8971 and MT8972, respectively.

They are multi-function 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).
  • ISDN compatible (2B+D) data format.
  • Transparent modem capability.
  • Frame synchronization and clock extraction.
  • Zarlink ST-BUS compatible.
  • Low power (typically 50 mW), single 5 V supply.
