Description
The MAX3735/MAX3735A are +3.3V laser drivers for SFP/SFF applications from 155Mbps up to 2.7Gbps. The devices accept differential input data and provide bias and modulation currents for driving a laser. DC-coupling to the laser allows for multirate applications and reduces the number of external components. The MAX3735/MAX3735A are fully compliant with the SFP MSA timing and the SFF-8472 transmit diagnostic requirements.

An automatic power-control (APC) feedback loop is incorporated to maintain a constant average optical power over temperature and lifetime. The wide modulation current range of 10mA to 60mA (up to 85mA AC-coupled) and bias current of 1mA to 100mA make this product ideal for driving FP/DFB laser diodes in fiber-optic modules. The resistor range for the laser current settings is optimized to interface with the DS1858 SFP controller IC.

The MAX3735/MAX3735A provide transmit-disable control, a single-point latched transmit-failure monitor output, photocurrent monitoring, and bias-current monitoring to indicate when the APC loop is unable to maintain the average optical power. The MAX3735A also features improved multirate operation. The MAX3735/MAX3735A come in package and die form, and operate over the extended temperature range of -40°C to +85°C.
