82V2082BFG8

Overview

The 82V2082BFG8 is a dual-channel Line Interface Unit (LIU) from the Renesas 82V2082 series, designed for E1/T1/J1 long-haul and short-haul applications. It operates on a single 3.3 V power supply with a voltage range of 3.13 V to 3.47 V. The device integrates adaptive equalization, clock data recovery, line decoding/encoding, and jitter attenuation within a single package. It is housed in a TQFP-128 surface-mount package and supports moisture-sensitive handling protocols.

Feature Summary

• Integrates adaptive equalizer for signal integrity maintenance
• Performs clock data recovery and line encoding/decoding
• Includes built-in jitter attenuator functionality

Applications

• E1/T1/J1 long-haul transmission systems
• E1/T1/J1 short-haul transmission systems
• Telecommunications interface units

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance details via official documentation. Check for updated packaging specifications as manufacturing processes may evolve. Ensure proper moisture barrier packaging is maintained prior to assembly to prevent damage during soldering.

Selection Notes

Select this component for dual-channel LIU requirements supporting both long-haul and short-haul modes. Verify compatibility with existing system voltage levels of 3.3 V. Consider the TQFP-128 package constraints for PCB layout. Evaluate thermal management needs based on the specific application environment.

Part Context

This part belongs to the 82V2082 family of telecom interface ICs. It serves as a successor or variant to earlier versions like the 82V2082PF. The BFG8 suffix indicates specific packaging and reel configuration differences compared to tray-packaged alternatives.

Replacement Considerations

The 82V2082PFG8 is listed as a direct alternative. Verify pinout and electrical parameter equivalence before substitution. Check for any functional differences introduced by packaging changes.
