摘要
采用0.18 μ m CMOS技术实现了用于千兆级无源光网络应用的全集成突发模式上游发送芯片。为了控制连续突发数据,本文提出的发射机采用以TX_enable作为突发包络信号的复位机制。来自监测光电二极管(MPD)的反馈通过两条独立的路径进行温度补偿。在1.25Gb/s突发模式下,采用片上配置测试的芯片平均功率为2dBm,消光比在12dB以上。经测试,本工作符合GPON ITU-T推荐标准G.984.2。
A fully integrated CMOS burst-mode upstream transmitter for gigabit-class passive optical network applications
A fully integrated burst-mode upstream transmitter chip for gigabit-class passive optical network applications is implemented in 0.18mum CMOS technology. In order to control consecutive burst data, the transmitter proposed in this paper uses a reset mechanism with TX_enable as a burst envelope signal. The feedback from the monitoring photodiode (MPD) is separated by two independent paths for temperature compensation. The chip tested with chip-on-board configuration shows an average power of 2dBm with extinction ratio of above 12dB under 1.25Gb/s burst- mode operation. Based on the measurement, this work complies with the GPON ITU-T Recommendation G.984.2.
