EL9111ILZ-T7

Overview

The EL9111ILZ-T7 is a triple channel differential receiver and equalizer manufactured by Renesas Electronics Corporation. It features three high-speed differential receivers with five programmable poles, where outputs are summed into an output buffer. Equalization length is controlled via a single voltage pin. The device offers ±5V supply operation, consuming 108mA total current. It provides a 150MHz -3dB bandwidth and supports CAT-5 cable compensation for lengths up to 1000ft at 50MHz or 500ft at 125MHz. The EL9111 variant specifically decodes sync signals encoded on the common modes of CAT-5 cables. It operates within a temperature range of -40°C to +85°C and is housed in a 28-lead QFN package.

Feature Summary

• Triple channel differential reception with integrated equalization for twisted-pair signal restoration
• Programmable gain adjustment per channel via VGAIN control signals
• Common mode sync decoding capability for horizontal and vertical synchronization extraction
• High impedance state enablement for parallel device connection and multiplexing applications

Applications

• Twisted-pair receiving and equalization systems
• KVM (Keyboard/Video/Mouse) switch interfaces
• VGA transmission over twisted-pair cabling
• 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. Check for obsolete product status and potential substitute availability. Ensure proper handling procedures for moisture sensitivity levels during storage and assembly.

Selection Notes

Select this component for applications requiring differential signal recovery over long twisted-pair distances. Consider the EL9111 variant if common mode sync decoding is necessary. Evaluate thermal requirements based on PCB layout and copper area for heat dissipation. Verify logic voltage levels match system reference potentials.

Part Context

This part belongs to the EL9111/EL9112 family of triple differential receivers. It is functionally similar to the EL9112 but includes specific sync decoding features. The device is designed for high-speed video signal transmission over standard cabling infrastructure.

Replacement Considerations

Public confirmed substitute: ISL59911. Verify pin compatibility and functional equivalence before substitution.

FAQ

How is the equalization length adjusted?

The equalization length is set by applying a control voltage between the VCTRL and VREF pins, typically ranging from 0V to 1V.

What is the purpose of the exposed die plate?

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

Can multiple devices be connected in parallel?

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