EL1537AIREZ-T13

Overview

The EL1537AIREZ-T13 is a DSL line driver manufactured by Renesas. It integrates two drivers within a single package, designed for digital subscriber line applications. The device operates on a 12V supply voltage and supports an operating temperature range from -40°C to 85°C. It utilizes a 28-HTSSOP surface-mount package with exposed pads, featuring a 0.173-inch (4.40mm) width. This component facilitates signal transmission in telecommunications infrastructure requiring robust line driving capabilities.

Feature Summary

• Integrates dual DSL line drivers for efficient signal processing
• Designed for harsh environmental conditions with extended temperature ratings
• Utilizes compact surface-mount packaging for space-constrained designs

Applications

• Digital Subscriber Line (DSL) equipment
• Telecommunications infrastructure
• Broadband access systems

Procurement Notes

Verify the manufacturer designation carefully, as the part number indicates Renesas production despite the query brand. Confirm the specific suffix requirements for tape-and-reel packaging versus tube quantities. Ensure compatibility with existing PCB footprints for the 28-HTSSOP package before procurement.

Selection Notes

Select this component when dual-channel DSL driving is required within a limited board area. Consider the 12V supply requirement and thermal management needs for the HTSSOP package. Verify that the -40°C to 85°C range meets the operational environment specifications of the target application.

Part Context

This component belongs to the Elantec semiconductor portfolio, which was acquired by Renesas Electronics. The EL1537 series represents legacy DSL interface solutions now managed under the Renesas brand. The part serves as a specialized interface chip for broadband communication hardware.

Replacement Considerations

Consult official Renesas documentation for direct cross-reference alternatives. Verify pin-to-pin compatibility and electrical parameter equivalence before substituting with other DSL drivers. Generic replacements may not match the specific integration level or package constraints.
