EL9112ILZ-T13S2714

Overview

The EL9112ILZ-T13S2714 is a triple channel differential receiver and equalizer housed in a 28-lead QFN package. It operates on ±5V supplies with a total supply current of 108mA (36mA per channel). The device features a 150MHz -3dB bandwidth, a differential input range of 3.2V, and common-mode rejection ratios of -80dB at 10kHz and -55dB at 10MHz. It includes programmable equalization controlled by a single voltage pin and individual channel gain adjustment via VGAIN pins.

Feature Summary

• Triple-channel architecture with five programmable poles for CAT-5 cable compensation
• Single-pin control for equalization length and independent per-channel gain adjustment
• High-speed differential reception with 150MHz bandwidth and low offset voltage
• Logic-controlled enable and gain switching for multiplexing applications

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 T13S2714 against manufacturer documentation to confirm tape and reel specifications and lot traceability. Confirm RoHS compliance status as the base part is Pb-free plus anneal. Check for End-of-Life notices or obsolescence warnings prior to procurement.

Selection Notes

Select this component for high-speed differential signal recovery over lossy twisted-pair media. Ensure the application supports ±5V power rails and requires active equalization for cable lengths up to 1000ft. Verify thermal management requirements for the QFN package based on ambient temperature and PCB copper area.

Part Context

This part belongs to the EL9111/EL9112 family of triple differential receivers. The EL9112 variant provides standard RGB output without sync decoding, distinguishing it from the EL9111 which decodes horizontal and vertical synchronization signals encoded on the common modes of CAT-5 cables.

Replacement Considerations

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

FAQ

How is the equalization length adjusted?

Equalization length is set using the voltage applied to the VCTRL pin relative to the VREF pin, allowing compensation for cable losses up to approximately 100MHz.

What is the function of the exposed die plate?

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

Can multiple devices be connected in parallel?

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