    SI5383编程手册Page 11有Reg Map。以0xABCD为例,0XAB00为页地址,整个完整地址为0xABCD,在我们I2C对Si5383编程的时候,直接用clock builder配置出来的寄存器逐个写入即可。

SI5351使用i2c写入clock builder pro配置好的寄存器数据后频率异常?

ClockBuilder Pro软件会自动计算输入输出频率的频率合成参数,建议回读所配置寄存器。同时请确定下载新的配置方案(寄存器)时,必须按以下流程设置:关闭输出--》设置中断--》加载新的寄存器--》软复位--》使能输出。

sqmLOLThresh是SI5040 CDR的寄存器107-109中的14位值。 该值保留字段为RW,数据手册规定必须将它们写入某些非0值(107为0x20,109为0x05)。 从i2c总线读取这些寄存器时,我将这两个值都读取为全0。 我可以写任何我可以读回的值,但是在初始化时,它们会被清零。 其他寄存器中的其他保留位字段达到数据手册中指定的值,我对这3个寄存器需要做什么?

根据Si5040数据手册的5.8.1和6.4.1节。 寄存器107-109是索引寻址的,因此您不能直接对其进行读写。 您还必须另外使用数据手册中指定的寄存器106。 要阅读这些寄存器,您必须执行以下操作: 1、写寄存器106d = 04h 2、写寄存器106d = 44h 3、读寄存器107d 4、读取寄存器108d 5、读寄存器109d 您需要按照Si5040数据手册第5.8.1节和6.4.1节的规定将这些寄存器写入其中。

应用及方案  -  SILICON LABS  - 2017年10月03日 PDF 英文 下载

请推荐一款支持JESD204B接口标准的RRU应用芯片?

推荐使用无线通信专用时钟芯片Si5380,如果还需要支持gapped period模式,可以选择时钟芯片Si5383。Si5380/3是一款专门针对无线基站应用的时钟芯片,该时钟芯片针对无线通信应用领域可能使用到的频点都做了优化,非常适合RRU中使用。
