SiTime专为通信基础设施打造的MEMS时钟晶振
5G商用全面深化,5G-A规模化部署,工业无线专网普及,低空与高精度定位业务落地,让无线通信网络从传统"大带宽,广覆盖"迈入低时延,高可靠,纳秒级同步,高密度组网的全新阶段.相较于4G时代微秒级宽松时序容差,5GNR,TDD时分双工,MassiveMIMO,波束赋形,基站协同定位,工业TSN时间敏感传输等技术,对设备时钟精度,相位抖动,频率稳定度,跨节点时间同步提出了碾压式升级要求.
时序同步已经成为决定5G基站吞吐量,干扰抑制,切换成功率,定位精度与业务可靠性的底层核心指标.无数运营商与设备厂商实测证明:5G网络多数隐性故障,如小区干扰,吞吐波动,切换掉话,时延抖动,定位漂移,工业业务断连,根源并非射频与基带算法,而是终端与基站,DU/CU,AAU远端射频单元之间的时序偏差与时钟不稳定.
以SiTime为代表的高端MEMS精密定时技术,凭借纳秒级稳定度,超低抖动,超强环境适应性,可编程柔性定时,系统性解决5G无线基础设施的时序痛点,成为5G/5G-A基站设备,前传承载,边缘网关,工业专网的标配升级方案.
