Dual-Loop 50 Mbps–2.7 Gbps  
Laser Diode Driver  
a
ADN2841  
FEATURES  
GENERAL DESCRIPTION  
50 Mbps to 2.7 Gbps Operation  
Typical Rise/Fall Time 80 ps  
The ADN2841 uses a unique control algorithm to control both  
average power and extinction ratio of the laser diode (LD) after  
initial factory set up. External component count and PCB area are  
low as both power and extinction ratio control are fully integrated.  
Programmable alarms are provided for laser fail (end of life) and  
laser degrade (impending fail).  
Bias Current Range 2 to 100 mA  
Modulation Current Range 5 to 80 mA  
Monitor Photodiode Current 50 A to 1200 A  
Closed-Loop Control of Power and Extinction Ratio  
Laser Fail and Laser Degrade Alarms  
Automatic Laser Shutdown, ALS  
Dual MPD Functionality for DWDM  
Optional Clocked Data  
The ADN2841 has circuitry for a second monitor photodiode  
which enables DWDM wavelength control.  
Full Current Parameter Monitoring  
5 V Operation  
48-Lead LFCSP Package  
32-Lead LFCSP Package (Reduced Functionality)  
APPLICATIONS  
DWDM Dual MPD Wavelength Fixing  
SONET OC-1/3/12/48  
SDH STM-1/4/16  
Fiber Channel  
Gigabit Ethernet
