EL1528CRE

Overview

The EL1528CRE is a dual-channel differential DSL line driver manufactured by Intersil, now part of Renesas Electronics. Designed for ADSL2+ applications, this integrated circuit operates within a 20-pin HTSSOP package. It functions as a high-performance line driver specifically engineered to interface with digital signal processors in asymmetric digital subscriber line systems, providing the necessary signal conditioning and amplification for transmission over copper telephone lines.

Feature Summary

• Dual-channel architecture supporting simultaneous differential signal processing
• Optimized for ADSL2+ standard compliance
• Integrated line driver functionality for direct DSP interfacing

Applications

• ADSL2+ modem line interface circuits
• Digital Subscriber Line access multiplexers (DSLAMs)
• Asymmetric digital subscriber line network equipment

Procurement Notes

Verify manufacturer lineage from Intersil to Renesas Electronics when sourcing components. Confirm package type matches the 20-lead HTSSOP specification. Ensure documentation references the specific EL1528CRE suffix to distinguish from other variants in the family. Cross-reference datasheets for electrical characteristics relevant to ADSL2+ implementations.

Selection Notes

Select this component for designs requiring dedicated dual-channel differential driving capabilities for ADSL2+ standards. Evaluate thermal performance within the HTSSOP enclosure relative to system power constraints. Verify compatibility with upstream digital signal processor voltage levels and interface requirements before integration into the final hardware design.

Part Context

This device belongs to the Intersil/Renesas lineup of DSL interface solutions. The EL1528 series addresses the physical layer transmission needs for broadband access networks. As an evolution of earlier DSL driver technologies, it supports higher data rates associated with ADSL2+ specifications while maintaining compatibility with existing copper infrastructure deployments.
