82P2288BBG8

Overview

The Renesas Electronics Corporation 82P2288BBG8 is a telecommunications interface integrated circuit functioning as an eight-channel T1/J1/E1 transceiver. It supports programmable short and long haul line configurations for E1, J1, and T1 protocols. The device operates within a supply voltage range of 3V to 3.6V and maintains functionality across an industrial temperature range of -40°C to +85°C. It achieves data rates up to 2.048Mbps and utilizes a 256-pin PBGA package with dimensions of 17x17mm.

Feature Summary

• Supports multi-protocol operation for T1, J1, and E1 standards
• Configurable for both short haul and long haul transmission distances
• Integrates adaptive equalization and clock recovery capabilities

Applications

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

Procurement Notes

Verify the specific suffix BBG8 against official Renesas documentation to confirm pinout compatibility and package specifications. Confirm current production status and lifecycle stage prior to design finalization. Ensure environmental compliance requirements match project constraints. Validate that the 256-PBGA footprint aligns with manufacturing capabilities.

Selection Notes

Select this component when designing systems requiring simultaneous handling of multiple T1, J1, or E1 channels. Consider the 256-pin BGA package size for board space limitations. Evaluate power consumption within the specified 3V to 3.6V range. Assess thermal management needs for the -40°C to +85°C operating environment.

Part Context

This part belongs to the 82P2288 family of high-performance telecom interface ICs. It serves as a key component in digital carrier transmission systems. The device integrates transceiver functions typically found in separate components, reducing system complexity. It complements other LIU products in the Renesas portfolio for complete line-side solutions.

Replacement Considerations

Consult official substitution lists for equivalent Renesas parts. Verify functional compatibility with alternative transceivers before implementation.
