EL9110IUZE9049

Overview

The EL9110IUZE9049 is a single-channel differential receiver and equalizer manufactured by Renesas Electronics Corporation. It features a high-speed differential receiver with five programmable poles, summed into an output buffer. The device operates on ±5V supplies, consuming approximately 33mA of supply current. It provides a -3dB bandwidth of 150MHz and supports CAT-5 cable compensation for lengths up to 1000ft. The unit includes three-statable outputs for multiplexing applications and allows gain adjustment via the VGAIN control signal. It is housed in a 16-lead Quarter Size Outline Plastic package (QSOP) and is specified for operation over the -40°C to +85°C temperature range.

Feature Summary

• Integrates a high-speed differential receiver with five programmable poles for signal equalization.
• Supports twisted-pair cable compensation with adjustable equalization length via a single voltage pin.
• Features three-statable outputs enabling parallel connection for multiplexing applications.
• Allows gain adjustment up or down by 6dB using the VGAIN control signal.

Applications

• Twisted-pair receiving and equalizer circuits
• KVM (Keyboard/Video/Mouse) systems
• VGA transmission over twisted-pair cables
• Security video signal processing

Procurement Notes

Verify the specific suffix E9049 against official manufacturer documentation to confirm if it denotes a unique marking code, tape-and-reel specification, or environmental compliance variant. Confirm current availability status as distribution channels may list this component as obsolete or limited stock. Ensure the ordering information matches the required package type and lead-free specifications before finalizing procurement.

Selection Notes

Select this component when designing systems requiring CAT-5 cable equalization for VGA or security video signals. Ensure the design accommodates ±5V power supplies and provides precise analog control voltages between 0V and 1V for the VCTRL and VGAIN pins. Verify that the logic reference levels align with the system's digital voltage rails to ensure proper enablement and gain switching functionality.

Part Context

The EL9110 belongs to the Intersil/Renesas family of differential receivers designed for video signal integrity over copper cabling. It addresses signal attenuation caused by resistive skin effect losses in twisted-pair cables. The device simplifies design by integrating equalization and gain control functions typically handled by discrete components, reducing board space and complexity in video transmission applications.

Replacement Considerations

Consult official datasheets for direct functional equivalents from Renesas or other manufacturers offering single-channel differential receivers with similar ±5V operation and QSOP-16 packaging. Verify that any substitute maintains comparable bandwidth, supply current, and control voltage requirements for VCTRL and VGAIN pins.
