ADN2531ACPZ-R7集成电路（IC）的激光驱动器规格书PDF中文资料

ADN2531ACPZ-R7属于集成电路（IC）的激光驱动器。由亚德诺半导体技术有限公司制造生产的ADN2531ACPZ-R7激光驱动器激光驱动器电源管理集成电路 (PMIC) 可用于提供一个或多个受控电流源，以从标称恒定电压电源为半导体激光器件供电。产品通常支持通过监控受驱动的激光器件发出的光功率而得到反馈，可广泛应用于光通信系统中；并因具有对提供给用电设备的电流进行高频调制的能力，而与执行类似功能的器件区分开来。

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.
