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 [email protected].
The ADN2844 offers a unique control loop algorithm and pro-
vides dual loop control of both average power and extinction ratio.
Programmable alarms are provided for laser fail (end of life) and
laser degrade (impending fail).
Both the ADN2844 and the ADN2845 are available as bare die.
The ADN2844 is also available in 5 mm ¥ 5 mm 32-lead LFCSP.
