MAX3736,pdf (SFP Laser Driver)

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.
