The MAX3740AETG+ is a high-speed VCSEL driver from Analog Devices, suitable for small-form-factor (SFF) and small-form-factor pluggable (SFP) fiber optic LAN transmitters. It integrates a bias generator, laser modulator, and comprehensive safety features, including automatic power control (APC) to maintain optical power over temperature and laser property variations.
This driver operates at speeds up to 3.2Gbps, capable of switching up to 15mA of laser modulation current and sourcing up to 15mA of bias current. It features adjustable temperature compensation to ensure optical extinction ratio specifications are met across the operating temperature range of -40°C to +85°C. The device interfaces with standards like SFF-8472 for timing and diagnostic requirements.
Designed for applications such as multirate SFP/SFF modules, Gigabit Ethernet, Fibre Channel, and InfiniBand optical transmitters, the MAX3740AETG+ is housed in a compact 4mm x 4mm, 24-pin thin QFN package with an exposed pad. Its safety circuits are compliant with SFF and SFP multisource agreements (MSAs), detecting faults that could lead to hazardous light levels and disabling the VCSEL output.
The MAX3740AETG+ supports common cathode and differential configurations. It offers a bias current range of 1mA to 15mA and a modulation current range of 2mA to 15mA. Optional peaking current can be utilized to improve VCSEL edge speed. The device operates from a voltage supply of 2.97V to 3.63V.
