MAX3949ETE+T

Overview

The MAX3949ETE+T is a laser driver IC designed for SFP+ applications, supporting data rates from 1 Gbps to 11.3 Gbps. It operates within a supply voltage range of 2.7 V to 5.5 V and functions across an extended temperature range of -40°C to +85°C. The component utilizes a TQFN-16 package with exposed pad for thermal management.

Feature Summary

• Integrated laser driver optimized for high-speed optical transmission modules
• Supports variable data rates up to 11.3 Gbps for flexible system design
• Includes automatic power control (APC) loop functionality for stable output

Applications

• SFP+ transceiver modules
• Fiber optic communication systems
• Data center interconnects

Procurement Notes

Verify the specific suffix 'E' indicates the industrial temperature grade and '+T' denotes tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the source document explicitly lists this part number as active or obsolete to avoid procurement errors.

Selection Notes

Select this component when designing SFP+ compliant optical links requiring drivers up to 11.3 Gbps. Evaluate the TQFN-16 footprint against PCB layout constraints. Consider the integrated APC features if external control loops are undesirable for the specific module architecture.

Part Context

This device belongs to the Maxim Integrated laser driver family, specifically engineered for small form-factor pluggable transceivers. It addresses the need for compact, high-performance drivers in dense networking equipment, replacing older discrete solutions with an integrated monolithic approach.

Replacement Considerations
