Драйверы для лазеров

ИС - драйверы лазерных диодов фирмы ADI работают на скорости от 50Mbps до 10.7Gbps с лазерами Фабри-Перо, DFB и Vcsel. Эти мкросхемы работают в системах MSA, таких как SFP с цифровой диагностикой SFF-8472, SFF, 4X Fiber Channel, XFP, Xenpak, X2 и MSA-300. В драйверах имеется двухпетлевой контроль уровня сигнала и средней мощности, температурная калибровка, не требуется компенсация старения лазера. Это снижает себестоимость модуля.

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
