82P20516DBFG8

Overview

The Renesas 82P20516DBFG8 is a sixteen-channel E1 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 device integrates adaptive equalization, clock data recovery, line decoding/encoding, and jitter attenuation functions. It is housed in a CABGA package configuration.

Feature Summary

• Integrates sixteen independent E1 channels for high-density line interface requirements
• Includes built-in adaptive equalizer and jitter attenuator for signal integrity
• Supports short-haul transmission environments with fixed loss of signal levels

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the device's End-of-Life status. Confirm that the specific CABGA package variant matches the required PCB footprint and thermal management specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring multiple E1 interfaces in a compact form factor. Ensure the design accommodates the specific 3.3V power supply tolerances and validates compatibility with the short-haul channel characteristics defined in the official datasheet.

Part Context

This part belongs to the 82P20516 family of programmable LIUs. It serves as a specialized interface solution for connecting digital telephony lines to network equipment, distinct from transceiver-only components by integrating full line coding and physical layer processing capabilities.

Replacement Considerations

The product has reached End-of-Life status. Engineers should evaluate alternative solutions from current Renesas portfolios or compatible third-party equivalents that offer similar channel counts and E1 protocol support.
