EL9111ILZ-T13

Overview

The EL9111ILZ-T13 is a triple-channel differential receiver and equalizer designed for high-speed signal processing. It features three independent channels with five programmable poles, providing bandwidth up to 150MHz. The device operates on ±5V supplies with a total supply current of 108mA. It includes an enable pin for high-impedance state control and individual gain adjustment per channel via VGAIN pins. The EL9111 variant specifically decodes sync signals encoded on CAT-5 cable common modes. It is housed in a 28-lead QFN package and specified for operation from -40°C to +85°C.

Feature Summary

• Triple differential receivers with five programmable poles for CAT-5 compensation
• Single-pin voltage control for equalization length adjustment
• Per-channel gain adjustment capability with additional switchable drive gain
• Common mode sync decoding functionality specific to the EL9111 model

Applications

• Twisted-pair receiving and equalization 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 direct manufacturer channels. Confirm RoHS compliance status and Pb-free anneal specifications as indicated in ordering information. Check for obsolete product notices and potential discontinuation risks before finalizing procurement plans.

Selection Notes

Select the EL9111 variant when sync decoding from CAT-5 common modes is required. Choose the EL9112 for standard differential reception without sync decoding. Ensure thermal pad connection to -5V for proper operation. Verify logic reference levels match system requirements for ENABLE and X2 pins.

Part Context

This component belongs to the EL9111/EL9112 family of triple differential receivers manufactured by Renesas Electronics Corporation, formerly Intersil. These devices are engineered for video signal integrity restoration over lossy transmission media like twisted-pair cables.

Replacement Considerations

Public datasheets identify ISL59911 as a possible substitute product. Verify functional compatibility and pinout alignment before implementation.

FAQ

How is the equalization length adjusted?

The equalization length is set using the voltage applied to the single VCTRL pin relative to the VREF pin.

What is the function of the exposed die plate?

The exposed die plate must be connected to the -5V supply to ensure proper thermal dissipation and electrical operation.

Can multiple devices be connected in parallel?

Yes, the ENABLE pin allows outputs to be placed into a high-impedance state, enabling parallel connection for multiplexing applications.
