MAX3738ETG+T Description

Short technical summary and product information.

The MAX3738ETG+T is a +3.3V laser driver engineered for multi-rate transceiver modules, supporting data rates from 155Mbps to 4.25Gbps. It features automatic power control (APC), modulation compensation, and on-chip thermal compensation to maintain a constant optical extinction ratio over temperature and lifetime.

 

This device accepts differential data input signals and offers a wide modulation current range up to 85mA (AC-coupled) and bias current range up to 100mA, making it suitable for driving FP/DFB lasers in fiber optic modules. External resistors are used to set the required laser current levels. The MAX3738ETG+T includes transmit disable control (TX_DISABLE), bias-current monitoring, photocurrent monitoring, and a latched failure output (TX_FAULT).

 

It is compliant with SFF-8472 transmitter diagnostic and SFP MSA timing requirements. The MAX3738ETG+T is housed in a 4mm x 4mm, 24-pin thin QFN package and operates over an extended temperature range of -40°C to +85°C. It is ideal for applications such as Multirate OC-3 to OC-48 FEC Transceivers, Gigabit Ethernet SFF/SFP and GBIC Transceivers, and 1Gbps/2Gbps/4Gbps Fibre Channel SFF/SFP and GBIC Transceivers.
