在高速通信和控制系统中,机械振动引起的相位噪声成为主要的性能瓶颈。当石英晶体受外力的影响时,压电的内部效应产生的寄生电压将直接降低时钟信号。实验表明,1G的加速度可能会使典型振荡器的相位噪声恶化为20 dbc/hz(数据资源:IEEETr。Tr。Ultrason。Froelectr。Freq。Control。68)。本文将揭示一系列工业验证的四步优化政策。本文指出:●切割竞争的过程:SC切割晶体显示绝对好处 - γ矢量(加速度敏感性)为0.1 ppb/g,在切割(BLIL实验室测试报告)的1 ppb/g(BLIL实验室测试报告)●包装结构的进化范围更大的频率频率:Vibration的频率较大的频率范围的频率为60%,这是10倍。h as shown in Figure 1 Comparative Data) Two-point Packaging Vibration Curve Curve (Source: Bliley Technical White Paper) Uses dual-modal excitation detection Methods: 1.
