XRT5894IV-F

Overview

The XRT5894IV-F is a telecom interface integrated circuit manufactured by MaxLinear, designed as a four-channel E1 Line Interface Unit (LIU). It operates within a supply voltage range of 3.3 V to 5 V and supports an operating temperature range from -40°C to +85°C. The device is housed in a TQFP-64 surface-mount package. Power dissipation specifications are listed at 590 mW or 1.24 W depending on conditions. This component is classified under Telecom Interface ICs and is currently marked as obsolete with restricted availability.

Feature Summary

• Provides four independent channels for E1 line interface functionality
• Supports dual voltage operation at 3.3 V or 5 V
• Designed for industrial temperature environments ranging from -40°C to +85°C

Applications

• E1 telecommunications network infrastructure
• Digital cross-connect systems
• Telecom base station equipment

Procurement Notes

This component is officially discontinued and no longer in active production. Availability is strictly limited through existing distributor stock or secondary market sources. Verification of the specific lot date code and authenticity is critical due to the obsolescence status. Buyers should confirm the exact revision level and ensure compatibility with existing system designs before acquisition.

Selection Notes

Engineers requiring this specific four-channel E1 LIU must account for its end-of-life status when designing new products. Alternative solutions from the same manufacturer family or competing vendors should be evaluated for pin-to-pin compatibility and functional equivalence. Design-in efforts should prioritize components with guaranteed long-term supply agreements to mitigate future production risks associated with obsolete silicon.

Part Context

The XRT5894IV-F belongs to the MaxLinear XRT series of telecom interface devices. It serves as a specialized solution for handling E1 digital signals in telecommunications applications. The 'IV' suffix typically denotes the industrial temperature grade and specific packaging variant. As part of the broader portfolio, it addresses the need for multi-channel line interfacing in legacy and modern telecom hardware.

Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Engineers should consult MaxLinear documentation for recommended migration paths or contact technical support for specific replacement recommendations based on application requirements.
