82V2048ADAG8-CER

Overview

The 82V2048ADAG8-CER is an octal T1/E1 Line Interface Unit (LIU) manufactured by Renesas Electronics. It operates on a single 3.3 V power supply with a maximum voltage of 3.47 V and a minimum of 3.13 V. The device draws 55 mA of operating current and supports both parallel and serial interfaces. It is housed in a 144-lead TQFP package suitable for surface mount installation. The component functions within a temperature range of -40°C to +85°C and is classified as a short-haul line interface for telecom applications.

Feature Summary

• Provides integrated line interface capabilities for eight T1 or E1 channels
• Supports flexible system integration through parallel and serial interface options
• Designed for short-haul telecommunications transmission environments

Applications

• T1/E1 short-haul line interface circuits
• Telecommunications network equipment
• Digital subscriber line systems

Procurement Notes

Verify the exact suffix configuration, as the provided model includes '8-CER' which may indicate specific packaging or environmental compliance distinct from standard listings. Confirm availability status directly with authorized distributors, as this component family has faced discontinuation notices. Ensure RoHS compliance documentation matches the specific manufacturing date code required for your assembly process.

Selection Notes

Select this component when designing systems requiring multiple T1/E1 line drivers in a compact form factor. Verify that the 144-pin TQFP footprint fits the PCB layout constraints. Ensure the design accommodates the specified 3.3 V supply tolerance and thermal requirements for the industrial temperature range. Check if the parallel or serial interface mode aligns with the host processor capabilities.

Part Context

This part belongs to the 82V2048 series of Line Interface Units. It is functionally related to variants such as the 82V2048DAG and 82V2048BB. These components are widely used in legacy and modern telecom infrastructure for signal conditioning and line driving. The series represents a standard solution for multi-channel digital telephony interfaces.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 82V2048 family, such as the 82V2048DAG. Verify if newer generations from Renesas offer equivalent functionality with updated packaging or enhanced features. Consult official replacement guides for any obsolescence notifications affecting this specific LIU type.
