激光驱动器

ADI公司的激光二极管驱动IC支持FabryPerot激光器, 分布式反馈激光器(DFB)和Vcsel 激光器所使用的50 Mbps ～10.7 Gbps的数据速率。它还支持多元协议(MSA)模块, 例如带有SFF-8472数字诊断功能的SFP, SFF, 4x光纤通道, XFP, Xenpak, X2和MSA-300模块。由于具有消光比和平均功率自动双环路控制功能, 所以不需要对激光器老化和退化补偿所需的温度校准。因此降低了光发送器(TOSA)和模块成本。

ADN2531- 11.3 Gbps, Active Back-Termination, Differential Laser Diode Driver

ADN2531: 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 Ω to 140 Ω. The active back-termination in the ADN2531 absorbs signal reflections from the laser diode side of the output transmission lines, More

ADN2872- 3.3 V Dual-Loop, 50 Mbps to 3.3 Gbps Laser Diode Driver

ADN2872: 3.3 V Dual-Loop, 50 Mbps to 3.3 Gbps Laser Diode Driver

Like the ADN2870, the ADN2872 laser diode driver is designed for advanced SFP and SFF modules, using SFF-8472 digital diagnostics. The device features dual-loop control of the average power and extinction ratio, which automatically compensates for variations in laser characteristics over temperature and aging. The laser needs only be calibrated at 25°C, More
