EL9112ILZ-T7

Overview

The EL9112ILZ-T7 is a triple differential receiver and equalizer manufactured by Renesas Electronics Corporation. It integrates three high-speed differential receivers with five programmable poles, summing outputs into a buffer for signal restoration. The device features a 150MHz -3dB bandwidth and operates on ±5V supplies with a typical supply current of 36mA per channel. It provides CAT-5 cable compensation, adjustable gain control via VGAIN pins, and an enable function for multiplexing applications. Packaged in a 28-lead QFN format, it supports operation from -40°C to +85°C.

Feature Summary

• Triple-channel differential reception with integrated equalization for twisted-pair cables
• Single-pin voltage control for adjusting equalization length based on cable characteristics
• Per-channel gain adjustment capability with additional switchable drive matching
• High impedance output state enabled via logic control for parallel device connection

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 distributors or direct manufacturer channels. Confirm the specific T7 tape and reel packaging designation matches system requirements. Check for RoHS compliance status and lead-free annealing specifications as indicated in official documentation. Ensure the obsolete product status does not conflict with long-term availability needs.

Selection Notes

Select this component for applications requiring precise CAT-5 cable equalization across three differential channels. Verify that the ±5V supply architecture aligns with the system design. Consider the 28 Ld QFN package constraints regarding thermal dissipation and PCB layout. Evaluate if the 150MHz bandwidth meets the specific frequency response requirements of the target application.

Part Context

This part belongs to the EL9111/EL9112 series of triple differential receivers. While the EL9111 includes sync decoding capabilities, the EL9112 focuses purely on reception and equalization. Both share identical pinouts and electrical characteristics except for the sync decoding functions present only in the EL9111 variant.

Replacement Considerations

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