ADN2873ACPZ集成电路（IC）的激光驱动器规格书PDF中文资料

ADN2873ACPZ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ADN2873ACPZ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

Like the ADN2870, the ADN2873 laser diode driver (LDD) is designed for advanced SFP and SFF modules, using SFF-8472 digital diagnostics. The ADN2873 supports NRZ data transmission operation from 50 Mbps up to 4.25 Gbps. With a new alarm scheme, this device avoids the shutdown issue caused by the system transient generated from various lasers.
