Maxim Integrated MAX3737

The MAX3737 is a +3.3V laser driver designed for multirate transceiver modules with data rates from 155Mbps to 2.7Gbps. The APC loop maintains constant average optical power. Lasers can be DC-coupled to the MAX3737 for reduced component count and ease of multirate operation.

GENERAL DESCRIPTION

FEATURES

o Single +3.3V Power Supply o 47mA Power-Supply Current o 85mA Modulation Current o 100mA Bias Current o Automatic Power Control (APC) o Modulation Compensation o On-Chip Temperature Compensation o Self-Biased Inputs for AC-Coupling o Ground-Referenced Current Monitors o Laser Safety, Shutdown, and Alarm Outputs MAX3737 Laser extinction ratio control (ERC) combines the features of automatic power control (APC), modulation compensation, and built-in thermal compensation. Modulation compensation increases the modulation current in proportion to the bias current. These control loops combined with thermal compensation maintain a constant optical extinction ratio over temperature and lifetime. The MAX3737 accepts differential data input signals. The wide 5mA to 60mA (up to 85mA AC-coupled) modulation current range and up to 100mA bias current range makes the MAX3737 ideal for driving FP/DFB lasers in fiber-optic modules. External resistors set the required laser current levels.
