EL9112ILZ

Overview

The EL9112ILZ is a triple channel differential receiver and equalizer designed for high-speed signal restoration. It features three independent channels with five programmable poles, where equalization length is controlled via a single voltage pin (VCTRL). The device operates on ±5V supplies, drawing 39mA per channel, and provides a 150MHz -3dB bandwidth. Each channel allows 6dB gain adjustment via VGAIN pins, with an additional 6dB switchable gain. It supports a differential input range of 3.2V and common mode rejection exceeding 80dB at 10kHz.

Feature Summary

• Triple-channel architecture with integrated equalization for CAT-5 cable compensation
• Single-pin control for adjusting equalization depth based on cable length
• Per-channel gain adjustment capability to compensate for signal contrast errors
• High impedance output state enabled by logic control for multiplexing applications

Applications

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

Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm RoHS compliance status and Pb-free anneal specifications against the latest datasheet revision. Check for Obsolete status indicators as this part may be superseded by newer equivalents like the ISL59911. Ensure supply chain documentation matches the specific ordering suffix requirements.

Selection Notes

Select the EL9112ILZ when CAT-5 cable compensation is required for RGB video signals. Ensure the design utilizes ±5V power rails and accommodates the 28 Ld QFN package thermal requirements. Verify that the application does not require sync decoding, which is exclusive to the EL9111 variant. Confirm logic levels align with the VREF pin configuration for proper ENABLE and X2 control operation.

Part Context

The EL9112 belongs to the EL9111/EL9112 family of triple differential receivers. It shares identical electrical characteristics with the EL9111 but lacks the common-mode sync decoding functionality found in the EL9111. Both devices utilize the same 28 Ld QFN package and are intended for similar video transmission applications over twisted pair media.

Replacement Considerations

The ISL59911 is identified as a possible substitute product in official documentation. Verify pin compatibility and functional equivalence before implementation.
