82P2816ABBG

Overview

The Renesas 82P2816ABBG is a 16-channel plus one T1/E1/J1 short-haul Line Interface Unit (LIU). It integrates an adaptive equalizer, clock data recovery circuitry, line decoding and encoding logic, and a jitter attenuator. The device operates within a supply voltage range of 1.8V to 3.3V and supports a programmable Loss of Signal (LOS) level. Designed for surface-mount installation, it utilizes a 27.0 x 27.0 mm PBGA package with 341 leads and a 1.0mm pitch. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates adaptive equalization and clock data recovery for signal integrity maintenance
• Includes built-in line decoding and encoding capabilities
• Features a dedicated jitter attenuator for noise reduction

Applications

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

Procurement Notes

Verify the specific suffix 'BBG' against official Renesas documentation to confirm package dimensions and lead finish specifications. Confirm current production status as this series may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when a high-density LIU solution is required for short-haul T1, E1, or J1 applications. Compare channel count and package size against alternatives like the 82P2821BHG if higher channel density is needed. Verify power supply requirements match the 1.8V/3.3V dual-voltage specification.

Part Context

This part belongs to the Renesas 82P28xx family of telecom interface ICs. It serves as a specialized line interface unit designed to bridge digital cross-connect systems with physical transmission lines. The 82P2816 variant specifically targets short-haul applications requiring integrated signal conditioning.

Replacement Considerations

Check for direct pin-to-pin replacements within the 82P28xx series. Verify if the 82P2821BHG offers necessary channel expansion. Consult Renesas Product Change Notices for any process changes affecting equivalent parts.
