XRT82D20IWTR-F

Overview

The XRT82D20IWTR-F is a single-channel E1 Line Interface Unit (LIU) manufactured by MaxLinear. It serves as a telecom interface IC designed for digital subscriber line applications. The component operates within a specified voltage range and supports half-duplex communication protocols typical of E1 standards. It is housed in a surface-mount package suitable for automated assembly processes. The device integrates necessary circuitry to interface between the network physical layer and digital processing units, ensuring signal integrity over copper transmission lines.

Feature Summary

• Integrates complete line interface functionality for E1 digital carrier systems
• Supports standard telecommunications signaling requirements for network termination
• Designed for robust operation in industrial and telecom environments

Applications

• E1 digital subscriber line equipment
• Telecommunications network termination units
• Digital carrier interface modules

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Check for obsolescence notifications from MaxLinear regarding supply chain transitions. Ensure storage conditions adhere to moisture sensitivity level specifications prior to reflow soldering processes.

Selection Notes

Evaluate compatibility with existing E1 protocol stacks and physical layer requirements. Consider thermal management needs based on expected operating temperature ranges. Assess pinout compatibility if replacing legacy components in established designs. Verify power supply constraints align with system voltage rails to ensure stable LIU operation during peak data transmission periods.

Part Context

This component belongs to the XRT82D20 series of telecom interface integrated circuits. It represents a specialized solution for E1 line interfacing within MaxLinear's portfolio. The part is distinct from general-purpose transceivers due to its dedicated E1 protocol handling capabilities. It complements other interface solutions by providing targeted functionality for European digital hierarchy networks.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified sources. Consult MaxLinear technical support for approved cross-reference options or design-in alternatives that meet identical E1 specification requirements.
