EL1529IL

Overview

The EL1529IL is a dual-channel differential DSL line driver designed for Globespan CO chipsets. It operates on ±5V to ±12V supplies and delivers 450mA output drive capability with a 44.1VP-P differential output into 100Ω. The device features a high slew rate of 500V/µs, a bandwidth of 46MHz, and typically -85dBc THD at 1MHz. Supply current is adjustable via the IADJ pin or preset modes (C0 & C1 pins). It is housed in a 24-pin QFN package (4x5mm) and specified for operation from -40°C to +85°C.

Feature Summary

• Dual-channel differential architecture optimized for flat gain response and reduced harmonic distortion.
• Adjustable supply current control via external resistor or four pre-set operational modes.
• High channel separation performance exceeding 75dB across critical frequency bands.

Applications

• ADSL line drivers for Globespan G7566-850 CO chipsets
• High-performance long reach ADSL2 applications
• High speed ADSL2+ and G.Span systems

Procurement Notes

Verify component authenticity through authorized channels as this part is obsolete. Confirm RoHS compliance status if sourcing non-Z suffix variants. Ensure proper ESD handling during installation due to the small footprint QFN package. Validate thermal pad soldering requirements for reliable heat dissipation.

Selection Notes

Select this component only for existing designs utilizing Globespan G7566-850 chipsets. Evaluate power consumption requirements against the adjustable current modes. Consider the ±5V to ±12V supply range compatibility with system voltage rails. Verify PCB layout constraints for the 24-pin QFN package dimensions.

Part Context

The EL1529IL was manufactured by Intersil Corporation before its acquisition by Renesas Electronics. It serves as a specialized interface component within the signal chain for specific DSL modem architectures. The product has been discontinued and is not recommended for new designs.

Replacement Considerations

No recommended replacement is available. Contact Technical Support Center for potential alternatives.

FAQ
