82V2082PFG

Overview

The Renesas 82V2082PFG 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 integrated circuit. The device operates on a 3.3 V power supply with a specified range of 3.13 V to 3.47 V. It is housed in an 80-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. The component functions as a complete interface solution, handling line coding, decoding, and signal conditioning for digital carrier systems.

Feature Summary

• Integrates dual independent channels for simultaneous E1/T1/J1 line interfacing
• Supports configurable short-haul and long-haul transmission distances
• Provides comprehensive line interface unit functionality including encoding and decoding

Applications

• Telecommunications network infrastructure equipment
• Digital subscriber line access multiplexers (DSLAM)
• Network routers and gateways requiring E1/T1 connectivity

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's current datasheet to confirm RoHS compliance status and lead-free material specifications. Ensure the 80-TQFP package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel LIU solution is required for E1, T1, or J1 standards. Compare the 80-TQFP package constraints against available board space. Verify that the 3.3 V operating voltage aligns with the system power architecture and thermal management capabilities.

Part Context

This part belongs to the 82V2082 series of telecom interface ICs. It serves as a successor or variant to older packages like the 82V2082PF, which has been discontinued. The PFG designation specifically indicates the 80-lead TQFP surface-mount package configuration used in modern telecommunications hardware designs.

Replacement Considerations

The 82V2082PFG is listed as a direct replacement for the discontinued 82V2082PF. Both parts share identical functional specifications and pinouts, allowing for drop-in upgrades in existing designs without schematic modifications.
