82V2042EPF

Overview

The Renesas Electronics Corporation 82V2042EPF is a dual Line Interface Unit (LIU) designed for T1, E1, and J1 short-haul telecommunications applications. Operating at a nominal voltage of 3.3 V with a range of 3.13 V to 3.47 V, this integrated circuit provides two independent channels for line interface functions. It supports both serial and parallel interfaces for system connectivity. The component is housed in a surface-mount package and is rated for an operating temperature range from -40°C to +85°C. This device serves as a critical interface between digital signal processors and the physical transmission lines in telecom infrastructure.

Feature Summary

• Dual-channel architecture supporting simultaneous T1, E1, and J1 line interface operations
• Integrated Line Interface Unit (LIU) functionality for direct connection to transmission media
• Compatibility with standard 3.3 V power supply requirements for modern telecom systems
• Support for both serial and parallel control interfaces for flexible system integration

Applications

• T1/E1/J1 short-haul line interface modules
• Telecommunications network equipment requiring dual channel LIU capabilities
• Digital subscriber line access multiplexers (DSLAMs)
• Network interface cards for carrier-grade communication systems

Procurement Notes

Verify the specific suffix 'EPF' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy variants may differ. Ensure availability through authorized channels due to potential limited stock situations for older generation telecom interface components.

Selection Notes

Select the 82V2042EPF when a dual-channel solution is required for short-haul T1/E1/J1 applications. Compare against single-channel alternatives like the 82V2081PPG if only one interface is needed. Verify that the 3.3 V operating voltage aligns with the target system's power domain. Consider the 128-pin TQFP package dimensions for PCB layout constraints compared to other family members.

Part Context

This component belongs to the Renesas 82V20xx series of telecom interface ICs, specifically focusing on Line Interface Units. It shares functional similarities with the 82V2044EPFG but offers dual-channel capability rather than octal. The part is distinct from the 82V2082PFG8, which supports long-haul applications. Understanding the distinction between short-haul and long-haul LIUs is essential for proper application selection within the broader portfolio.

Replacement Considerations

The IDT82V2042EPF8 is listed as an alias for this component. For pin-compatible replacements, evaluate the 82V2044EPFG for higher channel density or the 82V2082PFG8 for long-haul requirements. Always verify electrical parameters and package dimensions before substituting.
