LMK04806: oscin悬空

Part Number: LMK04806
Other Parts Discussed in Thread: LMK04832

你好,如果oscin悬空,clkout可以输出时钟吗

  • 您好,LMK04806的PLL1作为jitter cleaner,PLL2作为clock generation。

    而PLL2的参考时钟只能是OSCin,并且看内部架构,没有任何MUX可以路由到CLKin输入时钟,所以如果OSCin悬空的话,CLKOUT是没有时钟输出的。您可以考虑LMK04832 ,这款和LMK04806功能类似,但是有MUX可以是的CLKin作为PLL2的参考时钟。
