MAX3982UTE+

Overview

The MAX3982UTE+ is a high-speed, low-power 2:1 video multiplexer designed for SFP copper-cable applications. It functions as a preemphasis driver to enhance signal integrity over short-reach copper links. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports data rates up to 3.125 Gbps. It features a single differential output channel with integrated preemphasis capability to compensate for channel loss. The component is housed in a compact 16-TQFN (3x3 mm) surface-mount package with an exposed pad for thermal management.

Feature Summary

• Integrated preemphasis driver functionality for copper-cable signal enhancement
• High-speed 2:1 video multiplexing architecture
• Low-power operation optimized for small form-factor transceivers

Applications

• SFP copper-cable assemblies
• Short-reach serial communication interfaces
• Video distribution systems requiring signal equalization

Procurement Notes

Verify the specific suffix 'EUT' against the official Analog Devices datasheet to confirm the exact pinout and thermal pad configuration. Ensure that the 16-TQFN footprint matches the target PCB design guidelines. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing short-reach copper interconnects requiring active signal conditioning. The integrated preemphasis feature reduces external equalization requirements. Verify that the operating data rate aligns with the 3.125 Gbps specification. Consider the thermal performance of the exposed pad TQFN package for high-density layouts.

Part Context
