EL9112ILZ-T13

Overview

The EL9112ILZ-T13 is a triple channel differential receiver and equalizer housed in a 28-lead QFN package. It operates on ±5V supplies with a total supply current of 108mA (36mA per channel). The device features a 150MHz bandwidth, a differential input range of 3.2V, and a common-mode input range from -4V to +3.5V. It includes five programmable poles for CAT-5 cable compensation and allows individual channel gain adjustment via VGAIN pins. The exposed die plate must be connected to the -5V supply.

Feature Summary

• Triple-channel architecture with integrated equalization for twisted-pair signal restoration
• Single-pin voltage control adjusts equalization length to match specific cable lengths
• Per-channel gain adjustment capability to compensate for contrast variations
• High-impedance outputs enable parallel connection for multiplexing applications

Applications

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

Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Confirm RoHS compliance status and MSL classification before procurement. Ensure the ordering suffix matches the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component for high-speed differential signal recovery where CAT-5 cable attenuation compensation is required. Ensure the design supports ±5V power rails and provides adequate thermal dissipation for the QFN package. Verify that logic levels align with the VREF pin configuration for proper ENABLE and X2 control operation.

Part Context

This component belongs to the EL9111/EL9112 family of triple differential receivers. The EL9112 variant focuses on standard signal reception and equalization, whereas the EL9111 includes additional circuitry for decoding sync signals encoded on common modes. Both share identical electrical characteristics and packaging.

Replacement Considerations

Public datasheets identify ISL59911 as a possible substitute product. Verify functional compatibility and pinout alignment before implementation.
