82V2048BBG

Overview

The 82V2048BBG is an octal T1/E1 Line Interface Unit (LIU) manufactured by Renesas Electronics. It operates within a supply voltage range of 3.13 V to 3.47 V, with a nominal working voltage of 3.3 V. The device is housed in a PBGA-160 surface-mount package and supports SMD/SMT installation. Classified under Telecom Interface ICs, it belongs to the 82V2048 series and functions as a short-haul line interface for T1, E1, and J1 standards. The component exhibits moisture sensitivity and carries the Renesas trademark.

Feature Summary

• Integrates eight independent line interface channels for high-density telecom applications
• Supports T1, E1, and J1 short-haul transmission protocols
• Designed for surface-mount assembly in compact electronic systems

Applications

• Telecommunications network infrastructure equipment
• T1/E1/J1 line termination systems
• Short-haul digital subscriber line interfaces

Procurement Notes

This component is officially listed as End-of-Life (EOL) by Renesas Electronics. Distribution availability is restricted or unavailable in many regions. Verification of current stock status and alternative sourcing through authorized channels is required before procurement planning. Check official discontinuance notifications for timeline details.

Selection Notes

Engineers should evaluate the 82V2048BBG specifically for octal channel requirements in short-haul T1/E1/J1 environments. Due to its obsolete status, design-in decisions must account for long-term supply constraints. Verify that the PBGA-160 package dimensions and 3.3 V operating voltage align with the target system's mechanical and electrical specifications.

Part Context

The 82V2048BBG is part of the 82V2048 family of Line Interface Units. It serves as an octal variant designed for multi-channel telecom interfaces. Related parts in this lineage include the 82V2058 series for E1 applications and other LIU models offering different channel counts or protocol support within the Renesas telecommunications portfolio.

Replacement Considerations

Public documentation identifies the 82V2058BBG as an alternate product within the same discontinued family. Engineers should review datasheets for both components to ensure functional compatibility regarding channel count, protocol support, and pinout configurations before substitution.
