EL1537IREZ-T7R5234

Overview

The EL1537IREZ-T7R5234 is a dual-channel ADSL2 driver manufactured by Elantec, now supported through Renesas. It operates within a temperature range of -40°C to +85°C and features enable/disable functionality. The device draws a typical operating current of 7.5mA with a static current of 3.9mA. Packaged in a 28-HTSSOP format, it is designed for driving full-rate ADSL signals in both Central Office (CO) and Customer Premises Equipment (CPE) applications.

Feature Summary

• Supports ADSL2 signal transmission standards
• Includes enable and disable control functions

Applications

• Central Office (CO) equipment
• Customer Premises Equipment (CPE)
• ADSL2 signal driving circuits

Procurement Notes

Verify the manufacturer support status, as Elantec is a legacy brand now integrated into Renesas. Confirm the specific suffix T7R5234 matches your supply chain requirements. Ensure the 28-HTSSOP package dimensions align with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component for low-power ADSL2 applications requiring dual-channel output. Consider the specified operating current and static current levels for power budget calculations. Verify compatibility with CO and CPE interface requirements to ensure proper signal integrity and performance in the target deployment environment.

Part Context

Elantec Semiconductor was a high-performance analog IC brand acquired and supported through Renesas. This part belongs to the legacy Intersil-era product line, specifically focusing on ADSL drivers. The EL1537 series is designed for efficient signal driving in broadband access networks.

Replacement Considerations

Consult official Renesas documentation for direct cross-reference or substitute part numbers. Verify pinout and electrical specifications against potential alternatives to ensure functional equivalence in existing designs.
