KYOCERA京瓷晶振赋能光学模块与网络通信高精度运行
不同于普通消费电子,网络通信与光学模块的时序应用场景具备高速率,高密度,强干扰,全天候运行的特点,对晶振性能提出四大硬性标准,也是行业产品性能差异化的关键:
1.超低相位抖动,低噪声:100G/400G/800G高速光链路对时序抖动预算极其苛刻,微小的相位噪声就会引发信号失真,误码率飙升,必须依靠飞秒级低抖动晶振保障传输纯净度.
2.超高频率稳定度:通信基站,骨干网设备常年不间断运行,且面临温度,电压波动,要求晶振在宽温工况下保持极小频偏,避免频率漂移导致链路掉线,同步异常.
3.差分输出,强抗干扰:光模块与交换机PCB布局密集,电磁串扰严重,差分输出架构可通过共模抑制能力抵御干扰,保障高速信号长距离稳定传输.
4.小型化,高集成度:新一代光模块趋向微型化,轻薄化设计,紧凑封装晶振可节省PCB空间,适配高密度贴片布局,满足设备小型化迭代需求.
