CDCE62005外部辅助时钟25M不起振

Other Parts Discussed in Thread: CDCE62005EVM

 

原理图是按照开发板设计的(图中27PF的电容,实际为5PF)

寄存器试过默认的

也尝试过     x"81840120",x"81840101",x"81860102",x"eb860103",x"01860114",x"101c0b25",x"04be19a6",x"bd0037f7"

输入选为AUX,输出为SMARTMUX

但是都不起振,寄存器读写都正常

是仅仅配置这8个寄存器  25M就能起振,还是需要再有什么配置才能起振?

 

求助专家!!
