EL9112ILZS2714

Overview

The EL9112ILZS2714 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 an output buffer. The device features a 150MHz -3dB bandwidth and consumes 108mA on ±5V supplies. It supports CAT-5 compensation for cable lengths up to 1000ft at 50MHz or 500ft at 125MHz. Gain adjustment is available via VGAIN control signals, allowing ±6dB per channel plus a switchable 6dB boost. The component operates within a -40°C to +85°C temperature range and utilizes a 28 Ld QFN package.

Feature Summary

• Triple-channel differential reception with integrated equalization
• Single-pin voltage control for cable length compensation
• Per-channel gain adjustment capability
• High impedance state support for multiplexing applications

Applications

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

Procurement Notes

Verify the specific suffix S2714 against official manufacturer documentation, as standard listings typically utilize IL or ILZ designations. Confirm current product lifecycle status, as the base EL9112 series is marked obsolete in public records. Ensure compatibility with existing PCB layouts requiring a 28 Ld QFN footprint and verify thermal pad connection requirements for reliable operation.

Selection Notes

Select this component for applications requiring precise equalization of CAT-5 twisted pair cables. Ensure the system provides stable ±5V power supplies and a quiet 0V reference for the output stage. Verify that logic levels align with the VREF pin configuration. Consider the ISL59911 if a direct replacement from the same family is required due to obsolescence.

Part Context

The EL9112 belongs to the EL9111/EL9112 family of triple differential receivers. Unlike the EL9111, which includes common-mode sync decoding, the EL9112 focuses purely on signal reception and equalization. Both devices share identical electrical characteristics and packaging, differing primarily in internal logic for synchronization extraction found only in the EL9111 variant.

Replacement Considerations

Public datasheets identify the ISL59911 as a possible substitute product for the EL9112 series.
