你好:
咨询一下,对于LMK5B12204来说,当有一个外部10MHZ的参考信号输入PRIREF引脚或者是SECREF引脚,这个10MHZ必须是AC差分信号吗,还是也可以是DC单端信号

但是为何TICS Pro配置软件中有这句话,3. Select interface type. AC or DC buffer is auto-seletected based on reference frequency. If reference frequency is below 5 MHz, then use DC buffer. Otherwise, use AC buffer. To select interface types for AC buffer, refer to the 'Interface Type Selection Tips' in the XO wizard page. The same can be applied to PRIREF and SECREF. 并且输入10MHZ的时候自动配置为AC模式呢,和芯片手册有冲突
