Procurement Notes

This component has reached end-of-life status and is officially discontinued by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verification of authenticity and condition is critical when sourcing from non-authorized distributors. Buyers should confirm the specific revision and packaging integrity prior to acquisition due to the product's obsolete lifecycle stage.

Selection Notes

Engineers replacing this part must verify pin compatibility and electrical specifications against alternative LIU solutions. The transition may require adjustments to power supply filtering and signal conditioning circuits. Reviewing the original datasheet for precise timing parameters and thermal characteristics is essential to ensure seamless integration into existing hardware designs without functional degradation.

Part Context

The XRT82D20 series belongs to MaxLinear's portfolio of telecom interface integrated circuits. These components are specifically engineered for E1/T1 digital transmission standards. The family provides reliable line driving and receiving capabilities for public switched telephone networks and private branch exchange systems, serving as critical interface nodes between digital processors and physical transmission lines.

Replacement Considerations

No direct public substitute part numbers are confirmed for this discontinued component. Designers should evaluate generic E1 LIU alternatives from other manufacturers, ensuring strict adherence to the original 2.048 Mb/s data rate and SOJ-28 form factor constraints.
