XRT83L30IV-F

Overview

The XRT83L30IV-F is a single-channel Line Interface Unit (LIU) designed for T1 and E1 telecommunications applications. It supports both long-haul and short-haul transmission modes, providing the necessary interface between digital cross-connect systems and the physical transmission line. The component integrates transmitter and receiver circuits with echo cancellation capabilities to ensure signal integrity over varying line conditions.

Feature Summary

• Integrates full-duplex transmitter and receiver functions for a single channel
• Supports configurable long-haul and short-haul operational modes
• Includes integrated echo cancellation circuitry for improved signal quality
• Provides standard digital interface compatibility for telecom equipment

Applications

• T1/E1 line interface units in central office equipment
• Digital subscriber line access multiplexers (DSLAMs)
• Network synchronization and timing infrastructure
• Telecommunications test and measurement instruments

Procurement Notes

This component is classified as obsolete by the manufacturer. Availability is restricted to existing stock or third-party distributors. Verify authenticity through authorized channels and check datasheet revisions carefully, as legacy parts may have updated errata or pinout variations that impact compatibility with existing designs.

Selection Notes

Select this part when a single-channel LIU solution is required for T1 or E1 networks. Ensure the design accommodates the specific voltage levels and clocking requirements of the host processor. Consider the thermal characteristics of the TQFP-64 package if operating in high-density environments where heat dissipation is critical for long-term reliability.

Part Context

Part of the MaxLinear XRT83 series, which offers various multi-channel LIU solutions. This single-channel variant serves as a cost-effective alternative to multi-channel packages for applications requiring only one T1 or E1 connection, simplifying board layout and reducing power consumption compared to higher-channel-count counterparts.

Replacement Considerations

As an obsolete component, direct replacements are limited. Evaluate the XRT83L30I for potential pin-compatible alternatives within the same family, though availability must be confirmed. Cross-reference with newer generation LIUs from other manufacturers if redesigning the system, ensuring electrical parameters match the original specification.
