INTRODUCTION
The 2R, 3R, 4R Resistor Networks are the designers first choice for ultra high precision, stable and reliable Voltage Divider or Network.
The Z-Foil Technology provides a significant reduction of the resistive components sensitivity to ambient temperature variations (TCR) and applied power changes, self-heating (PCR). 0.05 ppm/°C Absolute TCR removes errors due to temperature gradients.
The 2R, 3R, 4R provide a unique, inherent combination of performance characteristics resulting in excellent performance and high reliability, satisfying the needs of today’s expanding requirements.
The availability of low absolute TCR and low PCR, provides a good cost solution for the variability of other components when compiling the total error budget.
Our Application Engineering Department is available to advise and to make recommendations for non-standard technical requirements and special applications, please do not hesitate to contact us.

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.
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 identically but with the DSIC having a shorter maximum loop reach specification. The generic "DNIC" will be used to reference both devices unless otherwise noted. The MT9171/72 is fabricated in Zarlink’s ISO2-CMOS process.

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

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
