EL9110IUZE9049-T7

Overview

The EL9110 is a single-channel differential receiver and equalizer designed for high-speed signal processing. It features a bandwidth of 150MHz and operates on a ±5V supply with a typical current consumption of 33mA. The device includes five programmable poles for equalization, adjustable via a single control voltage pin to compensate for cable length attenuation. Gain can be adjusted by ±6dB using the VGAIN control signal, with an additional X2 gain option. It offers a differential input range of 3.2V and common mode rejection ratio of 60dB at 10kHz. The component is housed in a 16-lead QSOP package and supports operation from -40°C to +85°C.

Feature Summary

• Integrates a high-speed differential receiver with five programmable equalization poles summed into an output buffer.
• Features a three-stateable output enabling parallel connection for multiplexing applications.
• Provides adjustable gain control via VGAIN pin and selectable X2 gain logic input.

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 ordering suffix against the manufacturer's official documentation to confirm packaging type and lead-free status. The EL9110 series has been discontinued; check for end-of-life notifications or alternative sourcing options before finalizing procurement plans.

Selection Notes

Select this component for applications requiring CAT-5 compensation up to 100MHz. Ensure the design accommodates the ±5V dual supply requirement and the specific logic reference voltage configuration needed for the ENBL, CMEXT, and X2 pins.

Part Context

The EL9110 belongs to the Intersil/Renesas family of differential receivers. It is specifically engineered to mitigate signal loss in twisted-pair cabling, commonly used in video and data transmission environments where maintaining signal integrity over distance is critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the product is discontinued, consult the manufacturer's official obsolescence notices for potential recommended replacements.

FAQ

How is the equalization length determined?

The equalization length is set by the voltage applied to the VCTRL pin, which adjusts the frequency response to match cable attenuation characteristics.

What is the function of the CMEXT pin?

The CMEXT pin enables common mode range extension, allowing the device to handle larger common mode voltages without overloading the input differential amplifier.

Can multiple EL9110 devices be connected in parallel?

Yes, the device features a three-stateable output, which allows multiple units to be connected in parallel for multiplexing applications.
