XRT59N97IV-F

Overview

The XRT59N97IV-F is a MaxLinear telecom interface IC designed for E1 line transmission. It integrates seven independent channels within a single package, supporting operation at standard voltages of 3.3V or 5V. The device operates across an extended industrial temperature range from -40°C to +85°C. It utilizes a 128-pin SQFP surface-mount package to facilitate high-density circuit board layouts. This component serves as a Line Interface Unit (LIU) for digital telecommunication networks.

Feature Summary

• Integrates seven independent E1 channel transceivers in a single integrated circuit
• Supports dual voltage operation for compatibility with 3.3V and 5V logic levels
• Designed for robust performance in harsh industrial environments with wide temperature tolerance

Applications

• E1 digital telecommunication network interfaces
• Telecom base station equipment
• Industrial communication systems requiring multi-channel E1 connectivity

Procurement Notes

This component is officially classified as obsolete by the manufacturer. Availability is restricted, and sourcing requires verification through authorized distributors or secondary market suppliers. Buyers must confirm current stock status and authenticity due to discontinuation. Replacement planning should be initiated immediately to mitigate supply chain risks associated with end-of-life products.

Selection Notes

Select this part only when seven-channel E1 integration is required. Verify that the system design supports both 3.3V and 5V power domains. Ensure the PCB layout accommodates the 128-pin SQFP footprint. Consider thermal management requirements for the specified operating temperature range during the design phase.

Part Context

The XRT59N97IV-F belongs to MaxLinear's family of telecom interface solutions. It provides a consolidated solution for E1 signal processing, reducing component count compared to discrete implementations. The device simplifies system architecture by combining multiple LIU functions into one package, enhancing reliability and reducing board space consumption.

Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Designers should evaluate newer generations of telecom interface ICs from MaxLinear or other manufacturers. Cross-reference pinouts and electrical specifications carefully when selecting alternative components.
