EL9112ILZ-T7S2714

Overview

The EL9112ILZ-T7S2714 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 -3dB bandwidth, a differential input range of 3.2V, and common mode rejection ratios of -80dB at 10kHz and -55dB at 10MHz. Equalization length is controlled via a single voltage pin to compensate for CAT-5 cable losses up to 1000ft. Each channel allows gain adjustment of ±6dB through a VGAIN control signal.

Feature Summary

• Triple channel differential reception with integrated equalization for twisted-pair cables
• Single-pin voltage control adjusts compensation levels for varying cable lengths
• Per-channel gain adjustment capability to optimize signal contrast
• High impedance output state enabled by logic control for multiplexing applications

Applications

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

Procurement Notes

Verify the specific suffix T7S2714 against manufacturer documentation, as standard datasheets list T7 or T13 tape and reel options. Confirm RoHS compliance status and MSL classification for Pb-free anneal materials. Check for Obsolete Product Lifecycle Notices or potential substitute recommendations such as ISL59911 before finalizing procurement plans.

Selection Notes

Select this component for designs requiring simultaneous reception of three differential video channels over long CAT-5 runs. Ensure the design supports ±5V power rails and provides a quiet ground reference for the 0V output pin. Verify that the thermal pad connection to -5V is implemented correctly to maintain specified junction temperatures and electrical performance.

Part Context

This part belongs to the EL9111/EL9112 family of high-speed receivers. While the EL9111 includes sync decoding capabilities, the EL9112 focuses purely on differential reception and equalization. Both share identical pinouts and electrical characteristics except for the sync decoding outputs found only on the EL9111 variant.

Replacement Considerations
