11.3 Gbps, Active Back-Termination,  
Differential Laser Diode Driver  
ADN2531  
FEATURES  
GENERAL DESCRIPTION  
3.3 V operation  
Up to 11.3 Gbps operation  
Typical 26 ps rise/fall times  
Bias current range: 10 mA to 100 mA  
Differential modulation current range: 10 mA to 80 mA  
Voltage input control for bias and modulation currents  
Data inputs sensitivity: 150 mV p-p differential  
Automatic laser shutdown (ALS)  
Crosspoint adjustment (CPA)  
The ADN2531 laser diode driver can work with directly  
modulated laser diodes, including vertical-cavity surface-emitting  
laser (VCSEL), Fabry-Perot (FP) lasers, and distributed feedback  
(DFB) lasers, with a differential loading resistance ranging from  
5 Ω to 140 Ω. The active back-termination in the ADN2531  
absorbs signal reflections from the laser diode side of the output  
transmission lines, enabling excellent optical eye quality even when  
the TOSA end of the output transmission lines is significantly  
mismatched. The ADN2531 is a SFP+ MSA-compliant device,  
and its small package and enhanced ESD protection provides  
the optimum solution for compact modules in which laser  
diodes are packaged in low pin-count optical subassemblies.  
VCSEL, FP, DFB laser support  
SFF/SFP/XFP/SFP+ MSA compliant  
Optical evaluation board available  
Compact, 3 mm × 3 mm LFCSP  
The modulation and bias currents are programmable via the  
MSET and BSET control pins. By driving these pins with control  
voltages, the user has the flexibility to implement various average  
optical power and extinction ratio control schemes, including a  
closed-loop or a look-up table control. The automatic laser shut-  
down (ALS) feature allows turning the bias on and off while  
simultaneously modulating currents by driving the ALS pin with  
a low voltage transistor-to-transistor logic (LVTTL) source.  
APPLICATIONS  
Optical transmitters, up to 11.3 Gbps, for SONET/SDH,  
Ethernet, and Fibre Channel applications  
SFF/SFP/SFP+/XFP/X2/XENPAK/XPAK MSA compliant  
300-pin optical modules, up to 11.3 Gbps  
The product is available in a space-saving, 3 mm × 3 mm LFCSP  
package and operates from −40°C to +100°C.
