EL1529ILZ

Overview

The Elantec EL1529ILZ is a DSL interface controller designed for high-performance long-reach applications. It operates within a supply voltage range of 5V to 12V and supports data rates suitable for ADSL2, ADSL2+, and G.DMT standards. The component features an integrated driver and receiver configuration, housed in a 24-VFQFN exposed pad surface-mount package. It ensures reliable signal transmission across various DSL protocols with a specified operating temperature range from -40°C to +85°C.

Feature Summary

• Supports multiple DSL protocols including ADSL2, ADSL2+, and G.DMT for versatile connectivity.
• Integrates both transmitter and receiver functions within a single compact package.
• Designed for high-speed and long-reach performance in digital subscriber line applications.

Applications

• ADSL2 modem implementations
• ADSL2+ network interface units
• G.DMT compliant broadband access equipment

Procurement Notes

Verify the specific suffix 'ILZ' against the manufacturer's current documentation to confirm pinout compatibility and thermal pad requirements. Ensure that the 5V to 12V supply rails align with the target system design before integration. Cross-reference the 24-VFQFN package dimensions with PCB layout constraints to guarantee proper soldering and heat dissipation during assembly.

Selection Notes

Select this component when designing systems requiring support for legacy and advanced DSL standards such as ADSL2+. Consider the wide operating temperature range for industrial or outdoor deployments. Evaluate the need for integrated driver/receiver capabilities versus discrete solutions to optimize board space and simplify signal integrity management in DSL transceivers.

Part Context

Elantec Semiconductor was a prominent provider of analog and mixed-signal integrated circuits. Many of its product lines, including the EL series, have been transitioned to Renesas Electronics following corporate acquisitions. This part represents the legacy Elantec engineering focused on high-performance interface controllers for telecommunications infrastructure.

Replacement Considerations

Consult Renesas Electronics for direct equivalents or updated versions of the EL1529 series. Verify if newer generations offer improved power efficiency or extended protocol support while maintaining pin-to-pin compatibility for existing designs.
