Description: 11.3 Gbps, Active Back-Termination, Differential Laser Diode Driver
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 ? to 140 ?. 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. |
