82V2082BFG

Overview

The Renesas Electronics Corporation 82V2082BFG is a dual-channel Line Interface Unit (LIU) designed for E1, T1, and J1 telecommunications applications. It supports both short haul and long haul transmission modes within a single device. The component operates on a 3.3 V power supply with a specified voltage range of 3.13 V to 3.47 V. It is housed in an FPBGA-81 surface-mount package suitable for SMD/SMT installation. The device integrates adaptive equalization, clock data recovery, line decoding/encoding, and jitter attenuation functions.

Feature Summary

• Dual-channel architecture supporting simultaneous E1, T1, or J1 signal processing
• Integrated adaptive equalizer for signal integrity maintenance across varying line conditions
• Unified design capability for both short haul and long haul transmission environments

Applications

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

Procurement Notes

Verify the specific suffix BFG against official datasheets to confirm the FPBGA-81 package configuration. Ensure compatibility with moisture sensitivity level requirements during storage and handling. Confirm that the 3.3 V operating voltage aligns with the target system's power delivery specifications before integration.

Selection Notes

Select this component when a dual-channel LIU solution is required for mixed E1/T1/J1 networks. The integrated equalizer reduces external component count compared to discrete solutions. Consider the FPBGA-81 package constraints for PCB layout density and thermal management requirements relative to other packages in the 82V2082 series.

Part Context

This part belongs to the 82V2082 family of telecom interface ICs manufactured by Renesas Electronics. It serves as a specialized Line Interface Unit distinct from framer components like the 82V2108. The device complements octal LIUs such as the 82V2048BB by providing a lower channel count option for specific port density needs.

Replacement Considerations

The 82V2082PFG is listed as a direct substitute for the discontinued 82V2082PF variant. Verify pinout and electrical parameter equivalence between the BFG and PFG suffixes before substitution.
