82P2917ABBG

Overview

The 82P2917ABBG is a 17-channel T1/E1/J1 short haul line interface unit manufactured by Renesas Electronics Corporation. It integrates an adaptive equalizer, clock data recovery, line decoding/encoding, and a jitter attenuator. The device supports E1, J1, and T1 line rates with programmable LOS levels and is optimized for short haul applications. It is housed in a PBGA package measuring 27.0 x 27.0 mm with a height of 2.2 mm, featuring 34 leads at a 1.6 mm pitch.

Feature Summary

• Integrates adaptive equalization and clock data recovery for signal integrity
• Performs line decoding and encoding functions
• Includes a dedicated jitter attenuator
• Supports multiple standard line rates including T1, E1, and J1

Applications

• SDH/SONET multiplexers
• Central office or PBX systems
• Digital access cross connects
• Remote wireless modules
• Microwave transmission systems

Procurement Notes

Verify the specific suffix 'BBG' against official Renesas documentation to confirm package type and material specifications. Ensure compatibility with existing board layouts regarding the 27.0 x 27.0 mm PBGA footprint and 34-lead configuration. Confirm that the short haul optimization aligns with the target network distance requirements.

Selection Notes

Select this component when a high-density 17-channel LIU is required for short haul T1/E1/J1 interfaces. Consider the integrated jitter attenuator and adaptive equalizer if signal conditioning is needed without additional discrete components. Verify that the PBGA package fits within the thermal and mechanical constraints of the design.

Part Context

This part belongs to the 82P series of line interface units designed for telecommunications infrastructure. It serves as a specialized solution for connecting digital subscriber lines and trunk circuits in central offices and remote sites. The 17-channel capacity allows for efficient integration in compact networking equipment compared to lower-density alternatives.

Replacement Considerations

The 82P2916A is a documented 16-channel variant within the same product family. Verify pinout compatibility and channel count differences before substitution. No other direct public substitutes are confirmed in the provided documentation.
