The MAX3736 is a compact, +3.3V multirate laser driver for SFP/SFF applications up to 3.2Gbps. The device accepts differential data and provides 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 wide 5mA to 60mA (85mA AC-coupled) modulation current range and 1mA to 100mA bias current make the MAX3736 ideal for driving FP/DFB laser diodes in fiberoptic modules. The laser current setting can be controlled by a current DAC, a voltage DAC, or a resistor. Very low power dissipation, small package size, and reduced component count, make this part an ideal solution for SFP-module applications. The MAX3736 is available in a small 3mm x 3mm, 16-pin thin QFN package. It operates over a -40°C to +85°C temperature range.
