DESCRIPTION

· The MAX3736 is a compact, +3.3V multirate laser driver designed for SFP/SFF applications up to 3.2Gbps.
· It 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 device is ideal for driving FP/DFB laser diodes in fiber-optic modules with a modulation current range of 5mA to 60mA (85mA AC-coupled) and bias current from 1mA to 100mA.
· It features low power dissipation, small package size, and reduced component count, making it suitable for SFP-module applications.
· Available in a 3mm x 3mm, 16-pin thin QFN package, operating from -40°C to +85°C.

FEATURES

· Fully compatible with SFP and SFF-8472 specifications.
· Programmable modulation current from 5mA to 60mA (DC-coupled) and 5mA to 85mA (AC-coupled).
