3.3 V、双环路、50 Mbps至3.3 Gbps激光二极管驱动器

与ADN2870相似，ADN2872激光二极管驱动器针对先进的SFP和SFF模块而设计，采用SFF-8472数字诊断技术。可以对平均功率和消光比(ER)进行双环路控制，以自动补偿激光特性随着温度变化和老化而发生的变动。激光器只需要在25°C进行校准，不需要进行昂贵且耗时的温度校准。ADN2872支持50 Mbps至3.3 Gbps范围内的单速率或155 Mbps至3.3 Gbps范围内的多速率。该器件采用新型报警方案，可避免因各种激光产生的系统瞬变所导致的关断问题。\n\n 平均功率和ER可以利用微控制器数模转换器(DAC)或可调电阻所提供的电压进行设置。该器件提供偏置和调制电流监控 • SFP/SFF和SFF-8472 MSA兼容\n• 提供SFP参考设计\n• 工作速率：50 Mbps至3.3 Gbps\n• 对平均功率和消光比进行双环路控制\n• 典型上升/下降时间：60 ps\n• 偏置电流范围：2 mA至100 mA\n• 调制电流范围：5 mA至90 mA\n• 激光失效报警和自动激光关断(ALS)\n• 偏置和调制电流监控\n• 工作电压：3.3 V\n• 4 mm x 4 mm LFCSP\n• 电压设定点控制\n• 电阻设定点控制;
