3.3 V Dual-Loop, 50 Mbps to 3.3 Gbps  
Laser Diode Driver  
ADN2872  
FEATURES  
GENERAL DESCRIPTION  
SFP/SFF and SFF-8472 MSA compliant  
SFP reference design available  
Any rate from 50 Mbps to 3.3 Gbps operation  
Dual-loop control of average power and extinction ratio  
Typical rise/fall time: 60 ps  
Bias current range: 2 mA to 100 mA  
Modulation current range: 5 mA to 90 mA  
Laser FAIL alarm and automatic laser shutdown (ALS)  
Bias and modulation current monitoring  
3.3 V operation  
Like the ADN2870, the ADN28721 laser diode driver is designed  
for advanced SFP and SFF modules, using SFF-8472 digital  
diagnostics. The device features dual-loop control of the average  
power and extinction ratio, which automatically compensates  
for variations in laser characteristics over temperature and aging.  
The laser needs only be calibrated at 25°C, eliminating the need  
for expensive and time consuming temperature calibration. The  
ADN2872 supports single-rate operation from 50 Mbps to  
3.3 Gbps, or multirate operation from 155 Mbps to 3.3 Gbps.  
With a new alarm scheme, this device avoids the shutdown issue  
caused by the system transient generated from various lasers.  
4 mm × 4 mm LFCSP  
Voltage setpoint control  
The average power and extinction ratio can be set with a  
voltage provided by a microcontroller DAC or by a trimmable  
resistor. The part provides both bias and modulation current  
monitoring, as well as fail alarms and automatic laser shutdown.  
The ADN2872, a SFF-/SFP-compliant laser diode driver, can  
work with the Analog Devices, Inc., ADuC7019/ADuC702x  
MicroConverter® family and the ADN289x limiting amplifier  
family, to form a complete SFP/SFF transceiver solution. The  
ADN2872 is available in a space-saving 4 mm × 4 mm LFCSP  
specified over the −40°C to +85°C temperature range.  
Resistor setpoint control  
APPLICATIONS  
Multirate OC3 to OC48-FEC SFP/SFF modules  
1×/2×/4× Fibre Channel SFP/SFF modules  
LX-4 modules  
DWDM/CWDM SFP modules  
1GE SFP/SFF transceiver modules
