ISL1539IRZ-T7

Overview

The ISL1539IRZ-T7 is a dual-port VDSL2 line driver manufactured by Intersil. It integrates four wideband operational amplifiers configured as two differential pairs to support high-power push/pull applications. The device features a 240MHz bandwidth and ultra-low distortion characteristics, specifically -89dBc at 1MHz with a 2VP-P output. It operates on ±12V supplies, providing a 1.1V headroom and over 360mA peak output current per port. Quiescent power consumption is adjustable via external logic pins, allowing selection between full power (27.2mA/port), medium (23mA/port), low (13.5mA/port), or off states (<0.5mA/port).

Feature Summary

• Integrates four wideband current feedback operational amplifiers for dual-port differential line driving.
• Offers adjustable quiescent power consumption through external control logic pins for power optimization.
• Supports high SFDR operation with low supply voltage requirements down to ±7.5V.

Applications

• VDSL2 line driver designs requiring high MTPR performance.
• High power push/pull line driver applications.
• Broadband communication systems utilizing differential signaling.

Procurement Notes

Verify the specific suffix 'T7' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer notifications. Check for End-of-Life (EOL) status or discontinuation notices from Renesas or Intersil before finalizing procurement plans.

Selection Notes

Select this component for applications demanding high bandwidth and low distortion in VDSL2 environments. Consider the adjustable quiescent current feature if thermal management or power efficiency is critical. Ensure the design supports the required ±12V supply rails to utilize the specified peak output current capabilities.

Part Context

This part belongs to the ISL1539 family of dual-port VDSL2 line drivers. It shares functional similarities with other members like the ISL1539AIRZ but may differ in specific electrical tolerances or package variations. The T7 suffix typically denotes the reel packaging format used for automated assembly processes.

Replacement Considerations

Direct substitutes include the ISL1539AIRZ for dual-port VDSL2 applications. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
