EL9111ILZ

Overview

The EL9111ILZ is a triple-channel differential receiver and equalizer designed for high-speed signal processing. It features three independent channels with five programmable poles, allowing adjustable equalization via a single control voltage pin. The device provides per-channel gain adjustment of ±6dB using VGAIN signals, plus an additional switchable 6dB gain stage. It operates on a ±5V supply, consuming approximately 108mA total current. Key specifications include a 150MHz bandwidth, a differential input range of 3.2V, and common-mode rejection ratios exceeding -55dB at 10MHz. The component is housed in a 28-lead QFN package.

Feature Summary

• Triple-channel architecture with integrated equalization and programmable pole compensation
• Per-channel analog gain control with switchable x2 output gain mode
• Common-mode sync decoding capability for horizontal and vertical synchronization extraction
• High common-mode rejection ratio and wide differential input range

Applications

• Twisted-pair receiving and equalization systems
• KVM (Keyboard/Video/Mouse) matrix switches
• VGA transmission over twisted-pair cabling
• Security video signal processing

Procurement Notes

Verify the specific suffix 'ILZ' to confirm lead-free compliance and RoHS status. Confirm that the thermal pad connection requirements are met during assembly. Check for obsolete status or end-of-life notices as this product line may have been superseded by newer equivalents.

Selection Notes

Select the EL9111ILZ when sync decoding from CAT-5 cables is required. Choose the EL9112 variant if sync decoding is unnecessary. Ensure the application supports ±5V supplies and requires a 150MHz bandwidth. Verify PCB layout capabilities for the exposed die plate thermal connection.

Part Context

This component belongs to the EL9111/EL9112 family of triple differential receivers manufactured originally by Intersil and now under Renesas Electronics. It serves as a specialized interface solution for transmitting RGB video signals over twisted-pair media while maintaining signal integrity through active equalization.

Replacement Considerations

The ISL59911 is identified as a possible substitute product in official documentation. Verify functional compatibility regarding pinout and electrical specifications before implementation.
