EL9110IUZS2714

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 switch available. It provides a three-statable output for multiplexing applications and supports CAT-5 compensation up to 1000ft.

Feature Summary

• Integrates a high-speed differential receiver with five programmable equalization poles summed into an output buffer.
• Features a three-statable output enabling parallel connection of multiple devices for multiplexing applications.
• Includes a common mode extension circuit that extends input common mode range by 2V to 3V when enabled.

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 component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level before assembly. Check for specific ordering suffixes that may indicate tape-and-reel packaging versus tube quantities. Ensure proper handling procedures are followed due to electrostatic discharge sensitivity.

Selection Notes

Select this component for applications requiring precise equalization of twisted-pair cables up to 1000ft. Ensure the system design accommodates the required ±5V power supply rails. Verify that logic levels align with the LOGIC_REF pin configuration. Consider thermal dissipation requirements based on ambient temperature and PCB layout constraints.

Part Context

The EL9110 belongs to the Intersil/Renesas family of differential receivers. It is specifically engineered for video and data transmission over lossy media like Cat-5 cabling. The device replaces discrete equalization components by integrating pole adjustment and gain control into a single QSOP package.

FAQ

How is the equalization length determined?

The equalization length is set by applying a control voltage between 0V and 1V to the VCTRL pin (Pin 2), referenced against CTRL_REF (Pin 1).

What is the function of the CMEXT pin?

The CMEXT pin (Pin 15) enables the common mode extension circuitry, which extends the input common mode voltage range by approximately 2V to 3V when held high.

How is the output drive capability configured?

The X2 pin (Pin 9) controls the gain stage; a high logic level activates the X2 gain mode, doubling the output drive capability compared to the unity gain state.
