82P20516DBFG

Overview

The Renesas 82P20516DBFG is a sixteen-channel E1-only Line Interface Unit (LIU) designed for short-haul telecommunications applications. It operates within a supply voltage range of 3.13V to 3.47V and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a CABGA package, providing the necessary interface capabilities for high-density network infrastructure.

Feature Summary

• Integrates sixteen independent E1 line interfaces into a single compact device
• Optimized specifically for short-haul transmission environments
• Supports programmable configuration options for flexible deployment

Applications

• Local Area Network (LAN) infrastructure equipment
• Wide Area Network (WAN) routing systems
• Wireless base station connectivity modules
• Network gateway devices

Procurement Notes

Verify the specific suffix DBFG against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm current lifecycle status as legacy components may have limited availability or require alternative sourcing strategies.

Selection Notes

Select this component when designing systems requiring multiple E1 channels without T1/J1 compatibility needs. Ensure the design accommodates the CABGA footprint and strictly adheres to the specified 3.3V power supply tolerances for reliable operation.

Part Context

This part belongs to the Renesas 82P series of telecom interface products. It serves as a specialized solution for E1 networks, distinct from multi-standard transceivers that support T1 or J1 protocols simultaneously.

Replacement Considerations

Consult official Renesas substitution guides for direct replacements. Verify pin-to-pin compatibility and electrical parameter alignment before considering any cross-reference parts.
