另一个例子是设计从内部时钟获取数据的系统，用来取代请求用户输入。

Another example is designing a system that gets the date from the internal clock instead of asking for input from users.

一些设备有两个时钟，一个用于“捕获”或者“显示”数据，另一个则用于提供将数据输入器件的时序。

Some devices have two clocks, one to "capture" or "display" data, and another to clock it into the device.

我读过的数据表，但找不到任何参考指定一个输入时钟频率。

I've read the datasheet but can't find any reference to specifying an input CLK frequency.
