EL1527CRE

Overview

The EL1527CRE is a dual-channel medium power differential line driver designed for central office and customer premise line driving in DMT ADSL solutions. It features high drive capability of 400mA while consuming only 7.5mA of supply current per amplifier from ±12V supplies. The device achieves typical distortion of less than -75dBc at 1MHz into a 50Ω load. It includes two control pins, C0 and C1, per channel to select full-IS power, 3/4-IS power, 1/2-IS power, and power-down disable modes. Available in a thermally-enhanced 28 Ld HTSSOP package, it operates over the -40°C to +85°C temperature range.

Feature Summary

• Dual channel differentiated amplifier with high drive capability
• Multiple power management modes via C0 and C1 control pins
• Maintains excellent distortion and load driving capabilities in lowest power settings
• Pb-free available (RoHS compliant)

Applications

• ADSL G.DMT and G.lite CO line driving
• G.SHDSL, HDSL2 line driver
• ADSL CPE line driving
• Video distribution amplifier
• Video twisted-pair line driver

Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status if required by local regulations. Check datasheet revisions before implementation. Ensure proper thermal management during installation due to HTSSOP package characteristics. Validate pinout compatibility with existing PCB layouts.

Selection Notes

Consider operating voltage requirements when selecting this component. Evaluate power consumption needs across different IS modes. Assess thermal performance requirements for the application environment. Verify signal integrity specifications against system distortion limits. Confirm package availability and lead times for production planning.
