ADN2531屬于集成電路（IC）的激光驅動器。由亞德諾半導體技術有限公司制造生產(chǎn)的ADN2531激光驅動器激光驅動器電源管理集成電路 (PMIC) 可用于提供一個或多個受控電流源，以從標稱恒定電壓電源為半導體激光器件供電。產(chǎn)品通常支持通過監(jiān)控受驅動的激光器件發(fā)出的光功率而得到反饋，可廣泛應用于光通信系統(tǒng)中；并因具有對提供給用電設備的電流進行高頻調(diào)制的能力，而與執(zhí)行類似功能的器件區(qū)分開來。

GENERAL DESCRIPTION

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.
