82V2042EPFG

Overview

The 82V2042EPFG is a dual Line Interface Unit (LIU) manufactured by Renesas Electronics Corporation, designed for T1/E1/J1 short-haul telecommunications applications. It operates on a single 3.3 V power supply with a specified range of 3.13 V to 3.47 V. The device integrates two independent LIU channels within a 128-pin Thin Quad Flat Package (TQFP) measuring 14x20 mm. This component serves as a critical interface between digital signal processors and the physical transmission line, facilitating compliant signal transmission in high-speed data networks.

Feature Summary

• Dual-channel architecture providing independent line interface capabilities for simultaneous T1 or E1 connections.
• Integrated compliance with standard telecommunication signaling requirements for short-haul network segments.
• Single-supply operation simplifying power distribution design within telecom equipment chassis.

Applications

• T1/E1/J1 short-haul line interface units
• Telecommunications network infrastructure equipment
• Digital subscriber line access multiplexers

Procurement Notes

Verify the specific suffix 'EPFG' against official Renesas documentation to confirm package type and RoHS status. Distributor listings may contain conflicting packaging information such as tape-and-reel versus tray. Confirm current availability status directly with the manufacturer, as legacy components often face limited stock or end-of-life constraints.

Selection Notes

Select this component when designing systems requiring dual-channel T1/E1/J1 connectivity in a compact surface-mount form factor. Ensure the PCB layout accommodates the 128-TQFP footprint dimensions. Verify that the system power supply strictly maintains voltage levels between 3.13 V and 3.47 V to guarantee proper operation and signal integrity.

Part Context

This part belongs to the Renesas 82V2042 family of telecom interface ICs. It is functionally related to other variants like the 82V2042EPF8, differing primarily in packaging configuration. The series supports various short-haul line interface applications across multiple telecommunications standards.

Replacement Considerations

Check for direct pin-compatible substitutes within the same Renesas family. Verify if alternative packages from previous manufacturers, such as IDT versions, are approved replacements. Confirm functional equivalence before swapping components in existing designs.
