EL1528CLZ

Overview

The EL1528CLZ is a dual-channel differential DSL line driver manufactured by Elantec, now part of Renesas Electronics. It is designed for ADSL2+ applications and housed in a 20-pin HTSSOP package. The device integrates two independent drivers to support symmetric or asymmetric data transmission over telephone lines. Key electrical characteristics include a supply voltage range typically spanning from 4.5V to 5.5V, with quiescent current specifications optimized for low power consumption during idle states. The component supports standard logic levels and includes protection features against output short circuits and thermal overload to ensure reliable operation in telecommunications infrastructure.

Feature Summary

• Dual-channel architecture supporting simultaneous upstream and downstream signal processing
• Integrated protection mechanisms for output short-circuit and thermal management
• Optimized for low-power operation in digital subscriber line applications

Applications

• ADSL2+ modem transceivers
• Digital Subscriber Line Access Multiplexers (DSLAM)
• Network interface units for broadband telephony

Part Context

The EL1528CLZ belongs to the EL1528 family of DSL line drivers. It shares functional similarities with variants such as the EL1528CRE-T13, differing primarily in packaging and manufacturing lot specifics. Elantec was acquired by Intersil, which subsequently merged with Renesas Electronics, making this component part of the broader Renesas portfolio for communication interfaces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should verify pin compatibility and electrical parameters with alternative dual-channel DSL drivers from current manufacturers before substitution.
