MT9171 Overview
The MT9171 (DSIC) and MT9172 (DNIC) are pin for pin patible 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. They use adaptive echo-cancelling techniques and transfer data in (2B+D) format patible to the ISDN basic rate.
MT9171 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 patible (2B+D) data format
- Transparent modem capability
- Frame synchronization and clock extraction
- Zarlink ST-BUS patible
- Low power (typically 50 mW), single 5 V supply
