XRT73LC00AIV

Overview

The XRT73LC00AIV is a single-channel Line Interface Unit (LIU) manufactured by MaxLinear, designed for DS3, E3, and STS-1 telecommunications applications. It integrates the necessary circuitry to interface digital transmission equipment with the physical line. The device supports standard framing formats required for these high-speed serial data streams. It operates within a specified voltage range suitable for telecom infrastructure. The component is housed in a surface-mount package, facilitating automated assembly in electronic manufacturing processes.

Feature Summary

• Integrates complete line interface functionality for DS3, E3, and STS-1 standards
• Supports standard framing formats for high-speed serial data transmission
• Designed for robust operation in telecommunications infrastructure environments

Applications

• DS3/E3/STS-1 Line Interface Units
• Telecommunications network equipment
• Digital transmission systems

Procurement Notes

Verify authenticity through authorized channels due to end-of-life status. Check for moisture sensitivity handling requirements during storage and reflow. Confirm package integrity and pin alignment before installation. Review datasheet for specific operating conditions and electrical characteristics relevant to the target application design.

Selection Notes

Select this component when a single-channel LIU solution for DS3, E3, or STS-1 interfaces is required. Consider the single-channel limitation compared to multi-channel variants like the XRT73L03 series if higher port density is needed. Ensure the design accommodates the specific power supply and thermal requirements outlined in the official documentation.

Part Context

This part belongs to the XRT73L family of Line Interface Units from MaxLinear, formerly Exar. The family includes multi-channel variants such as the XRT73L03A and XRT73L04 series. The 'C' designation typically indicates a single-channel configuration within this product line, distinguishing it from the three-channel 'A' or four-channel 'B' options.

Replacement Considerations

The XRT73LC00AIV is listed as End-of-Life. Potential substitutes include other single-channel LIUs from MaxLinear or competitors supporting DS3/E3/STS-1 standards. Verify pinout compatibility and electrical specifications against alternatives like the XRT73L00 series variants.
