10.709 Gbps Laser Diode  
Driver Chipset  
a
ADN2843  
FEATURES  
GENERAL DESCRIPTION  
Data Rates from 9.952 Gbps to 10.709 Gbps  
Typical Rise/Fall Time 25 ps/23 ps  
Bias Current Range 3 mA to 80 mA  
Modulation Current Range 5 mA to 80 mA  
Monitor Photodiode Current 50 ꢀA to 1200 ꢀA  
Closed-Loop Control of Both Average Optical Power  
and Extinction Ratio  
Laser Fail and Laser Degrade Alarms  
Automatic Laser Shutdown, ALS  
Dual MPD Functionality for Wavelength Control  
CML Data Inputs  
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.  
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).  
50 ꢁ Internal Data Terminations  
3.3 V Single-Supply Operation  
Driver Supplied in Dice Format  
Both the ADN2844 and the ADN2845 are available as bare die.  
The ADN2844 is also available in 5 mm ¥ 5 mm 32-lead LFCSP.  
APPLICATIONS  
SONET OC-192, SDH STM-64  
Supports 10.667 Gbps and 10.709 Gbps FEC Rates  
10 Gb Ethernet IEEE802.3ae
