ADN2843 - 10.709 Gbps Laser Diode Driver Chipset

General Description

The ADN2943 chipset consists of two components, the ADN2845 and the ADN2844.

The ADN2845 is a 10.709 Gbps laser diode driver.

The ADN2845 eliminates the need to ac couple since it can deliver 80 mA of modulation while dc coupled to the laser diode.

Key Features
