我们试了两种场景，先上电，再拉高CE，
1. 直接读下寄存器，MUOUT始终低电平，能确认时芯片把它拉低的。
2. 给R0寄存器写0x0003值，然后再写0x0000值，进行个软复位，再读寄存器，然后MUOUT仍然是低电平
感谢您对TI产品的关注！
关于你的咨询， 你参考一下下面的muxout的说明
When CSB is HIGH, SPI activity is ignored. So the SDI and SCK signals can be shared with multiple devices but the CSB must be independent to each other.
If MUXout of Chip#1 is set to readback, then MUXout is an output pin. It is normally LOW unless a "1" is being read back.
MUXout is actually sampled by the rising edge of SCK.
根据规格书，写寄存器顺序已修改倒序；MUOUT有返回，波形如图片，配置寄存器见附件
1、MOUT波形异常，是什么问题造成？
2、当前配置2GHz输出，帮忙检查配置是否OK
