MAX3984UTE+

Overview

The MAX3984UTE+ is a high-speed cable equalizer and driver designed for data rates up to 8.5 Gb/s. It operates on a single 3.3 V supply with an operating current of 120 mA. The device integrates preemphasis capabilities and receive equalization to compensate for signal loss in copper cables. It is housed in a compact 16-lead QFN package (QFN-16) suitable for surface mount technology. The component supports a minimum operating temperature of 0°C and a maximum of +85°C, ensuring reliable performance in standard commercial environments.

Feature Summary

• Integrates transmit preemphasis and receive equalization functions within a single chip
• Supports high-speed serial data transmission up to 8.5 Gb/s
• Designed for low-power operation using a single 3.3 V supply voltage

Applications

• High-speed serial communication links
• Cable equalization for copper interconnects
• Data transmission interfaces requiring signal integrity compensation

Procurement Notes

Verify the specific suffix against official Maxim Integrated documentation to confirm pinout and electrical characteristics. Ensure the procurement channel provides genuine components with traceable origin. Check for RoHS compliance status as indicated in the manufacturer's certification records. Confirm that the QFN-16 package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when designing systems requiring integrated equalization and driving capabilities for copper cables at speeds up to 8.5 Gb/s. Consider the 3.3 V supply constraint and 120 mA current consumption during power budgeting. The QFN-16 package requires appropriate thermal management and soldering techniques suitable for fine-pitch surface mount assembly. Verify compatibility with the system's operating temperature range of 0°C to +85°C.

Part Context

The MAX3984UTE+ belongs to the Maxim Integrated family of high-speed interface solutions. It complements other transceivers and drivers by providing essential signal conditioning for long copper runs. The device addresses signal attenuation and distortion issues common in high-speed digital communications. Its integration reduces board space compared to discrete equalizer designs.
