82V2088BBG

Overview

The Renesas Electronics Corporation 82V2088BBG is an octal Line Interface Unit (LIU) designed for T1, E1, and J1 telecommunications standards. It supports both short haul and long haul transmission applications within a single device. The component operates on a 3.3 V power supply with a voltage range of 3.13 V to 3.47 V. It is housed in a 160-pin PBGA package measuring 15.0 x 15.0 mm with a height of 1.76 mm. The unit features an integrated adaptive equalizer, clock data recovery, line decoding/encoding capabilities, and a jitter attenuator.

Feature Summary

• Integrates adaptive equalization for signal integrity maintenance across varying line conditions.
• Performs clock data recovery and line encoding/decoding functions internally.
• Includes a dedicated jitter attenuator to improve signal timing accuracy.
• Supports configurable LOS levels for flexible network deployment.

Applications

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

Procurement Notes

Verify the current lifecycle status before integration, as this component may be subject to discontinuation notices. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure the specific package variant matches the PCB footprint design. Cross-reference official datasheets for any recent process change notices that might affect pin compatibility or material composition.

Selection Notes

Select this component when an octal LIU solution is required for mixed T1/E1/J1 environments. It is suitable for designs needing both short and long haul capabilities without switching components. Verify that the 160-pin PBGA package fits the available board space. Consider the thermal dissipation characteristics associated with eight simultaneous channels in the final enclosure design.

Part Context

This part belongs to the 82V20xx series of telecom interface ICs from Renesas. It serves as a high-density line interface solution for digital telephony networks. The device replaces older discrete solutions by integrating multiple physical layer functions into a single chip. It is commonly found in legacy and modern carrier-grade networking hardware requiring robust line signaling.

Replacement Considerations

Check for official end-of-life notifications from the manufacturer. Identify alternative parts within the same family that offer compatible pinouts. Verify if newer revisions maintain the same electrical specifications and package dimensions. Consult distributor databases for availability of surplus stock if immediate replacement is necessary.
