自己做了hmc1033的PCB板，用来产生500MHZ的时钟信号，写寄存器的代码如下：
HMC1033_Write(0x0A,0x2006); //reg AHMC1033_Write(0x08,0xC1BEfF);//reg8HMC1033_Write(0x0F,0x81); //reg fHMC1033_Write(0x07,0x14d); // reg7
HMC1033_Write(0x0B,0xF8061);//reg bHMC1033_Write(0x0C,0x0); //reg c
HMC1033_Write(0x02,0x02); //XTAL R,Step1 reg 2 HMC1033_Write(0x06,0x2003CA);//A/B Mode,Step2 reg6HMC1033_Write(0x09,0x10F264);//Charge Pump,Step3 reg 9
HMC1033_Write(0x05,0xFf88); // vco 01HMC1033_Write(0x05,0xF98); // vco 3HMC1033_Write(0x05,0x48B8); // vco 7HMC1033_Write(0x05,0x0); //vco 0
HMC1033_Write(0x03,0x50); //reg 3HMC1033_Write(0x04,0x0); //reg 4HMC1033_Write(0x05,0x210); //VCO Subsystem,Step4 vco2
写完之后能产生500M的时钟，且信号质量也很好，但锁定指示引脚为低电平。重要的是，过几分钟后，产生的时钟就会严重抖动。结果如下图所示。我觉得hmc1033一直都没有锁定才产生此情况。
但也找不出什么问题，也不懂怎么解决，请问是我写寄存器顺序或是方法错误 吗？真心求帮忙，十分感谢
楼主帮不了你，求大神过来看看。
请参考下面evb的寄存器：hmc1033_fracfb_LVPECL_Low_Noise
