Description

The MT9171AN is a multifunction electronic component in the telecommunication interface IC category. It is capable of providing high-speed, full-duplex digital transmission up to 160 kbit/s over a twisted wire pair. This component utilizes adaptive echo cancelling techniques and transfers data in the (2B+D) format, which is compatible with the ISDN basic rate. It can be easily interfaced with digital telecommunication networks and can also function as a high-speed limited distance modem. The MT9171AN has similar functionality to the MT9172AN, with the main difference being the shorter maximum loop reach specification of the DSIC. For simplicity, both devices are referred to as "DNIC" unless otherwise specified.

Specifications and Features

• Full duplex transmission over a single twisted pair
• Selectable 80 or 160 kbit/s line rate
• Adaptive echo cancellation
• Maximum reach of up to 3km (MT9171AN) and 4km (MT9172AN)
• ISDN compatible (2B+D) data format
• Transparent modem capability
• Frame synchronization and clock extraction
• MITEL ST-BUS compatible
• Low power consumption (typically 50 mW) with a single 5V supply

Application Scenarios

The MT9171AN is designed for various applications in the telecommunications field. It can be used for high-speed digital transmission over a single twisted pair, making it suitable for ISDN networks.
