MAX3956ETJ+TW

Overview

The MAX3956ETJ+T is a low-power Ethernet transceiver supporting data rates up to 11.3 Gbps, featuring an integrated DML driver and Digital Diagnostic Monitoring (DDM). It operates on a single 3.3 V supply with voltage limits between 2.85 V and 3.47 V. The device utilizes a TQFN-32 package for surface-mount installation. Designed for high-speed serial communication, it integrates transmitter and receiver functions within a compact form factor suitable for dense PCB layouts.

Feature Summary

• Integrates a Distributed Feedback Laser (DFL) driver and monitor photodiode circuitry
• Supports Digital Diagnostic Monitoring (DDM) for real-time performance tracking
• Provides low power consumption optimized for high-density networking applications

Applications

• 10 Gigabit Ethernet (10GbE) optical links
• Single-mode fiber optic transmission systems
• Data center interconnects requiring low power dissipation

Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation, as variations may exist. Confirm RoHS compliance status through the manufacturer's current datasheet. Ensure the ordering part number matches the specific tape-and-reel packaging requirements for your assembly line.

Selection Notes

Select this component when designing 10GBase-LR or similar single-mode fiber interfaces. Evaluate thermal management capabilities due to the integrated laser driver. Compare power budget constraints against system-level requirements to ensure the 3.3 V operation aligns with available power rails.

Part Context

This part belongs to the Maxim Integrated MAX395x family of high-speed optical transceivers. It serves as a key component in modern Ethernet infrastructure, replacing older discrete driver solutions. The ETJ+ designation indicates a lead-free, halogen-free variant compliant with environmental standards.

Replacement Considerations

Check for MAX3956AETJ+T variants which may include updated firmware or minor electrical tweaks. Verify pin-to-pin compatibility before substituting with other 11.3 Gbps transceivers from different manufacturers.
