82V2081PPG8

Overview

The 82V2081PPG8 is a single-channel Line Interface Unit (LIU) designed for E1, T1, and J1 digital transmission systems. It operates on a 3.3 V power supply with a voltage range of 3.13 V to 3.47 V. The device supports both short haul and long haul applications and integrates adaptive equalization, clock data recovery, line decoding/encoding, and jitter attenuation functions. It is housed in a 44-TQFP package with dimensions of 10x10 mm. The component is rated for an operating temperature range from -40°C to +85°C and has a maximum power dissipation of 1.41 W.

Feature Summary

• Integrates adaptive equalizer and clock data recovery for signal integrity
• Supports E1, T1, and J1 line rates for versatile telecom interfaces
• Includes built-in line decoding and encoding capabilities
• Features integrated jitter attenuator for improved signal quality

Applications

• LAN and WAN router implementations

• Telecommunications gateways

Procurement Notes

Verify the specific suffix 'G8' indicates reel packaging and RoHS compliance against official Renesas documentation. Confirm current production status as this part number may be subject to discontinuation notices. Ensure compatibility with existing 44-TQFP footprints and 3.3 V logic levels during integration planning.

Selection Notes

Select this component for single-channel E1/T1/J1 interface requirements where space efficiency is critical. Compare against dual-channel variants like the 82V2082 if higher port density is needed. Verify that the -40°C to +85°C industrial temperature range meets the environmental specifications of the target deployment location.

Part Context

This LIU belongs to the 82V2081 series of telecom interface ICs manufactured by Renesas Electronics. It serves as a physical layer interface solution for connecting digital subscriber lines to network equipment. The device replaces older discrete solutions by integrating multiple analog and digital functions into a single semiconductor package.
