Purchase must see! Electronic component selection from entry to give up

Basic knowledge of crystal vibration, circuit design, non-vibration reasons, circuit principle, crystal frequency, digital circuit application (crystal vibration data download)

In the standard 51 MCU system, we generally use the crystal frequency is 12MHz, and due to the architecture of the 51 MCU itself, its one machine cycle is exactly 12 clock cycles, so that the use of 12Mhz crystal can just adjust the machine cycle to 12x(1/12)us=1us.However, when communicating, 12MHz serial communication is not easy to achieve the standard baud rate (baud rate divider also needs to be divided by the system clock), such as 9600,4800.11.0592MHz can just be accurately divided into the bit rate ....
