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. It is intended to be copackaged with the laser to minimize bond lengths, which improves performance of the optical transmitter. For transmission line applications, contact HSN Application Group at fiberoptic.ic@analog.com.
