EL1526ILZ

Overview

The EL1526ILZ is a dual-channel differential DSL line driver manufactured by Elantec Semiconductor. It is designed for use with Centillium Maximus CO chipsets to support high-performance ADSL applications, enabling downstream spectrum usage up to 3.75MHz. The device provides a 450mA output drive capability and achieves a 44.1Vp-p differential output into a 100Ω load. Key electrical specifications include a -85dBc total harmonic distortion at 1MHz with a 2VP-P signal, a bandwidth of 46MHz, and a high slew rate of 500V/µs. Channel separation is specified at -80dB at 500kHz and -75dB at 1MHz.

Feature Summary

• Supports extended ADSL downstream spectrum up to 3.75MHz for payload rates up to 50Mbps when used with High-Bit-Loading features.
• Optimized for flat gain response and reduced harmonic distortion to improve overall system signal-to-noise ratio.
• Internal compensation circuit eliminates the need for external common mode snubber filters in active termination applications.

Applications

• ADSL line drivers for Centillium Maximus CO chipsets
• High-performance ADSL systems requiring extended spectrum support
• Signal chain components for High-Bit-Loading (HBL) implementations

Procurement Notes

Verify the manufacturer status as Elantec Semiconductor was acquired by Intersil, which was subsequently acquired by Renesas Electronics. Confirm current production availability and RoHS compliance details through official Renesas or authorized distributor channels, as legacy documentation may reference Intersil branding.

Selection Notes

Select this component specifically for designs utilizing Centillium Maximus CO chipsets where extended ADSL spectrum support beyond 1.1MHz is required. Ensure the application benefits from the internal compensation that removes the need for external common mode snubber filters. Verify compatibility with the target chipset's signal requirements for High-Bit-Loading operations.

Part Context

The EL1526ILZ belongs to the EL1526 series of dual-channel differential DSL line drivers. This series is engineered to integrate seamlessly with Centillium Maximus CO chipsets, providing the necessary drive capabilities and signal integrity for advanced ADSL deployments. The 'ILZ' suffix typically denotes an industrial temperature range and lead-free packaging compliant with RoHS standards.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Due to the specific integration with Centillium Maximus CO chipsets and proprietary optimization for High-Bit-Loading, direct pin-compatible replacements may not exist without significant circuit redesign.
