MAX3956ETJ+W

Overview

The MAX3956ETJ+W is a high-speed Ethernet transceiver designed for 11.3 Gbps data rates, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates a direct-modulation laser (DML) driver and supports Digital Diagnostics Monitoring (DDM) for real-time performance tracking. The device operates on a single 3.3 V supply with a voltage range of 2.85 V to 3.47 V. Packaged in a TQFN-32 form factor, it functions within an industrial temperature range of -40°C to +85°C. This component serves as a compact solution for optical transmission interfaces requiring low power consumption and integrated monitoring capabilities.

Feature Summary

• Integrates a DC-coupled laser interface with built-in DML driver circuitry
• Supports Digital Diagnostics Monitoring (DDM) for continuous link health assessment
• Operates at serial data rates up to 11.3 Gbps for high-bandwidth applications

Applications

• 10 Gigabit Ethernet (10GbE) optical transmission modules
• Fiber optic communication systems requiring digital diagnostics
• Data center interconnects utilizing direct-modulation lasers

Procurement Notes

Verify the specific suffix 'W' against official Analog Devices documentation to confirm package or temperature variations. Confirm current availability status through authorized distributors, as lead times may vary. Ensure compliance with RoHS directives and check for any obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when designing 11.3 Gbps optical links that require integrated laser driving and diagnostic feedback. Compare power dissipation specifications against thermal constraints of the TQFN-32 package. Evaluate compatibility with the target fiber optic module's electrical requirements and ensure the 3.3 V supply rail meets the specified operating range.
