Product Description

Product Details
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 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.
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 shutdown (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.
The product is available in a space-saving, 3 mm × 3 mm LFCSP package and operates from −40°C to +100°C.
