MAX3738ETG+T

Overview

The MAX3738ETG+T is a laser driver IC designed for SFF and SFP optical transceivers. It supports data rates from 155 Mb/s to 4.25 Gb/s. The device operates on a single 3.3 V supply with a typical operating current of 47 mA. It is housed in a TQFN-24 package suitable for surface mount installation. The component functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed serial data transmission up to 4.25 Gbps
• Integrated extinction ratio control functionality
• Optimized for small form-factor pluggable transceiver modules

Applications

• SFF (Small Form-factor Pluggable) optical transceivers
• SFP (Small Form-factor Pluggable) optical transceivers
• Fiber optic communication systems requiring 155Mbps to 4.25Gbps speeds

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check current availability as distribution may be limited or restricted. Ensure the supplier provides valid traceability for Analog Devices/Maxim Integrated components.

Selection Notes

Select this component for designs requiring a dedicated laser driver for SFF/SFP applications. Verify that the system power budget accommodates the 47 mA operating current. Ensure the PCB layout supports the TQFN-24 thermal requirements. Confirm compatibility with the target fiber optic module interface specifications.
