There are many different (and often confusing) terms associated
with clock-based devices. This application note attempts
to clarify these terms, and hence serves as a comprehensive
reference on clock terminology. This application note can be
divided into two sections. The first section describes and distinguishes
between various clock sources available today.
The second section defines and distinguishes between various
parameters used to describe clocks. This section also provides methods of measuring some of these parameters.

仿真步骤如下: 1、把3个帖子的内容分别保存为51t9py.c,51t9py_indexa.h,5py_mb.h,放在同一目录下,将51t9py.c加入工程编译 2、由于Keil的模拟串口是单字节显示,汉字显示为乱码,所以要加挂RICHWIN或RichView这种会重新刷新显示的中文平台,或手工刷新屏幕,所以请先到 http://www.pchome.net/dl/chinese.htm 下载RichView,安装运行 3、在Keil环境下可以直接按“Ctrl+F5”键仿真,按“F5”全速运行,切换到在串口依次输入: // 64*.6 426***.5 98*.7 936.3 586.1 4826*.1 9464*.7 64*.6试试:-) 4、按键对应(根据我自己的手机设置的,全部在PC的小键盘操作): -simulation steps are as follows : 1 and 3 respectively, the content of messages posted on the preservation of 51t9py.c, 51t9py_indexa.h, 5py_mb.h, on the same directory, will join the project 51t9py.c compiler 2, Keil is the simulation of single-byte Serial show , the Chinese showed gibberish, so need to add or RichView RICHWIN this show will re-set the Chinese platform, or manual refresh screen, so please download RichView http://www.pchome.net/dl/chinese.htm to install three operations in Central Keil Habitat can be directly "Ctrl+ F5" key simulation, according to the "F5" running full-speed, switched to the ser
