MAX3738ETG+ Description

Short technical summary and product information.

The MAX3738ETG+ is a +3.3V laser driver IC from Analog Devices, engineered for multi-rate transceiver modules operating at data rates from 155Mbps to 4.25Gbps. This device integrates Automatic Power Control (APC), modulation compensation, and thermal compensation to maintain a constant optical extinction ratio over temperature and lifetime.

 

Key electrical specifications include a wide modulation current range of 5mA to 60mA (up to 85mA AC-coupled) and a bias current range up to 100mA, making it suitable for driving FP/DFB lasers in fiber optic modules. It operates from a single +3.3V power supply and consumes approximately 47mA of power-supply current. The device features transmit disable control (TX_DISABLE), bias-current monitoring, and a latched failure output (TX_FAULT).

 

Packaged in a 4mm x 4mm, 24-pin Thin QFN (TQFN) package with an exposed pad, the MAX3738ETG+ is designed for surface mounting. It operates reliably over an extended temperature range of -40°C to +85°C, making it suitable for demanding applications.

 

Applications include 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.
