82P2828BHG

Overview

The 82P2828BHG is a telecommunications interface integrated circuit manufactured by Renesas Electronics. It functions as a 28-channel High-Density Line Interface Unit (HD LIU). The device supports E1 line interface applications, providing the necessary physical layer connectivity for digital telecommunication networks. It is designed for surface-mount installation in a PBGA-640 package. The component is classified as an End-of-Life product, indicating it is no longer in active production.

Feature Summary

• Integrates 28 independent channels within a single high-density package
• Provides dedicated hardware support for E1 standard line interfacing
• Optimized for compact board layouts in telecom infrastructure equipment

Applications

• Central Office switching systems
• Private Automatic Branch Exchange (PABX) units
• Digital multiplexers and demultiplexers

Procurement Notes

This component has reached its end-of-life status and is officially discontinued by the manufacturer. Availability is restricted to existing stock held by distributors or third-party suppliers. Buyers should verify the authenticity of the source and check for potential manufacturing date code limitations before acquisition. Long-term supply continuity cannot be guaranteed through official channels.

Selection Notes

Engineers requiring this specific part number must evaluate alternative solutions due to its discontinued status. Design reviews should consider pin-compatible upgrades or functional equivalents from current Renesas portfolios to ensure long-term project viability. Supply chain risk assessment is recommended prior to finalizing any procurement plans involving obsolete inventory.

Part Context

The 82P2828BHG belongs to the 82P282x series of high-density line interface units. This family is engineered to consolidate multiple E1 interfaces into a single footprint, reducing overall system complexity and board space requirements compared to discrete channel implementations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Renesas technical support for current portfolio recommendations that replace the discontinued 82P2828BHG.
