MAX3721UTG+TG104

Overview

The MAX3721UTG+ is a laser printer driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3V to 3.6V and supports data rates up to 3.2 Gb/s. The device is housed in a 24-TQFN (4x4) package with exposed pad, suitable for surface mount installation. It functions as a single-channel driver designed for high-speed optical communication applications, featuring CML input/output interfaces. The component is rated for an operating temperature range of 0°C to +85°C and consumes approximately 37 mA of supply current under standard conditions.

Feature Summary

• Integrated laser printer driver architecture optimized for high-speed serial data transmission
• Supports differential CML input and output signaling for robust signal integrity
• Adaptive equalization capabilities to compensate for channel loss in copper media
• Compact 24-pin TQFN package design facilitating dense PCB layout

Applications

• SONET/SDH optical receiver front-ends
• XFP form-factor optical transceivers
• High-speed serial data links over copper or fiber
• Clock and data recovery (CDR) system inputs

Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet, as alphanumeric codes may indicate specific testing or binning criteria. Confirm RoHS compliance status through the latest environmental declaration. Ensure the supplier provides traceable documentation matching the Analog Devices part number to avoid counterfeit components. Check for any obsolete status notifications from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring a 3.2 Gb/s laser driver with integrated equalization features. Ensure the PCB layout accommodates the 24-TQFN package dimensions and thermal requirements. Verify that the power supply rails meet the 3.3V nominal specification with appropriate decoupling. Consider the operating temperature range if the application involves harsh environmental conditions outside the commercial grade limits.

Part Context

This part belongs to the MAX3721 series of high-speed optical drivers. It is commonly paired with clock and data recovery ICs like the MAX3991 in complete optical receiver solutions. The device addresses signal integrity challenges in short-reach interconnects by providing adaptive equalization. It represents a specialized solution within Maxim Integrated's portfolio for telecom and datacom optical modules.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly confirmed in public documentation. Evaluate alternative devices from the same family with compatible interface standards. Verify electrical parameter overlaps, particularly data rate and supply voltage, before substitution. Consult the manufacturer for updated lifecycle status and recommended new design alternatives.
