The ADN2843 is high-performance, 3.3 V laser diode driver supporting data-rates up to 10.7 Gbps. The ADN2843 uses a unique control algorithm to control both average power and extinction ratio of the laser diode after initial factory set-up. This enables consistent optical performance over temperature, as well as lifetime, diode processing variations, and diode supplier. The ADN2843 is specifically designed to be directly-coupled to the laser diode, providing the benefits of decreased cost, size, and power while significantly reducing pattern-dependent jitter that occurs in standard AC coupled applications. Programmable alarms are provided for laser fail (end of life), and laser degrade (impending fail).

The ADN2843 operates from a single power supply at +3.3 V. It is available as a chipset (see datasheet for details).
