82V2082PF8

Overview

The 82V2082PF8 is a dual-channel Line Interface Unit (LIU) designed for E1, T1, and J1 telecommunications applications. It supports both long-haul and short-haul transmission modes within a single integrated circuit. The device 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 80-pin Thin Quad Flat Package (TQFP-80), also designated as PQFP80 or LQFP. The component functions as a PCM transceiver with one functional unit per channel configuration. It is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Integrates dual LIU channels for simultaneous E1/T1/J1 line interface operations.
• Supports adaptive equalization and clock data recovery for signal integrity.
• Configurable for both long-haul and short-haul transmission distances.

Applications

• Telecommunications network infrastructure equipment
• Digital cross-connect systems
• Multiplexer units in carrier networks

Procurement Notes

This component is officially discontinued by Renesas Electronics. Verification of availability requires checking authorized distributors for remaining stock or approved obsolescence notices. Direct replacement parts may be available; verify pin compatibility and electrical specifications before integration into existing designs.

Selection Notes

Select this part for dual-channel E1/T1/J1 interface requirements requiring long-haul capabilities. Ensure the design accommodates the 80-TQFP package dimensions and 3.3 V power domain. Verify that the application does not require RoHS compliance if sourcing original inventory, as specific suffixes indicate lead-free status.

Part Context

The 82V2082PF8 belongs to the IDT/Renesas 82V2082 family of telecom interface ICs. It serves as a legacy solution for high-density digital line interfacing. The 'PF8' suffix typically denotes the 80-pin TQFP package and reel/cut-tape packaging format, distinguishing it from tray-packaged variants like the PFG suffix.

Replacement Considerations

The 82V2082PFG is listed as a direct substitute. Verify package equivalence and confirm discontinuation status through official Renesas Product Discontinuance Notices before procurement.
