MAX3656ETG

Laser Drivers Overview

The MAX3656ETG is a burst-mode laser driver designed for optical transceivers operating at data rates from 155Mbps to 2.5Gbps. It accepts PECL or CML data inputs and provides bias and modulation currents for laser diodes. The device features a digital automatic power control loop, enabling constant average optical power across temperature variations without external capacitors. It supports turn-on times under 2ns and operates on a single +3.3V supply with typical quiescent current of 40mA. Packaged in a compact 24-pin TQFN.
