【经验】超低相位噪声抖动衰减时钟乘法器Si5382相噪指标差的原因解析和解决方案
Si5382是SILICON LABS的一款超低相位噪声抖动衰减时钟乘法器，专为需要最高集成度和相位噪声性能、超低分频和功耗的无线基站而优化。Si5382接收4个从0.008到750 MHz的时钟输入，并生成从0.000001到2949.12 MHz的12个时钟输出。Si5382基于Silicon Labs的第四代DSPLL技术，该设备将频率合成和抖动衰减结合在一个高度集成的数字解决方案中，去掉了对外部VCXO和环路滤波器组件的需求。外挂一个低成本、固定频率振荡器提供自由运行和保持模式的频率稳定性，目前仍然在不少的无线基站设备中作为高速收发器的参考时钟获得非常多的应用。
Si5382的应用场景多，势必会碰到一些应用问题，特别是关于分频器的配置问题，尽管可以使用CBPro软件进行优化，但是有些特定场合，还是需要特别对输入或者时钟配置方案做一些调整才能获得最佳的性能输出。日前有工程师在使用Si5382时发现其在10MHz和253.44MHz输入时，输出JESD204B时钟及其它时钟的相噪指标很差。在经过与AE等专家交流后发现其问题根本原因来自于其输入侧的分频器，如下警告，表示这个小数分频会额外导致输出相噪。
实际上Si5382的输入结构显示，在输入信号进入DSPLL之前，需要经过P0/P1的分频器再经过输入选择器（类似于crossbar）选择进入DSPLL，工作时只能选择一个输入。为了平衡输入，这两个参数在通过CBPro软件配置时，一般会自动优化设置，但是对于10MHz和253.44MHz这两个频点都可能需要分频后输入到DSPLLB的时钟信号，其分频参数与单端一个输入到DSPLLB是不一样的，需要综合考虑两个输入频点，这里输出122.88M时，由于内部VCO设置，253.44MHz的P1必须使用小数分频器，同时在同一个DSPLLB，导致IN0的10MHz的P0也会使用小数分频器，小数分频器的使用本身相对于整数分频会可能导致输出相噪的变差。
这种情况下怎么优化呢？主要有两种方法：
联系原厂直接使用特定方法更改CBPro内部设置，调整P0和P1，因为P0针对的是IN0的10M，本身是不需要小数分频的，改成整数分频是可行的，这种内部调制需要联系原厂更改。
根据应用场景，进行优化处理，因为IN0的10MHz和IN1的253.44MHz两个频点是不能同时进入DSPLLB的，且这两个频点不是整数倍关系，不存在无缝切换，切换也需要重新锁定跟踪过程，因此可以设置两组CBPro的工程文件，在使用其中一组针对IN0，另外一组针对IN1，输出一致，这样只设置IN0的输入10MHz自动设置为整数分频，可以优化输出相噪。如果需要切换IN1时，直接重新初始化Si5382，重新锁定即可。
