IC和晶振密切相关

Crystal is a very accurate clock source, which is widely used in digital circuits, microcontrollers and embedded systems.

晶振是一种精度极高的时钟源，它在数字电路、微控制器和嵌入式系统中被广泛使用。

Crystals can provide accurate clock signals required by electronic devices to determine the sampling time and timing control of the signal. Because modern electronic devices usually need high -precision clock signals to perform data synchronization and timing control, the application of crystal is widely used. In some systems that need to be synchronized with clocks, such as serial communication protocols, etc., crystals need to be used to provide accurate clock signals near the chip to ensure that the equipment work is normal.

晶振可以提供电子设备需要的精确时钟信号，以确定信号的采样时间和时序控制。因为现代电子设备通常需要高精度时钟信号来进行数据同步和时序控制，因此晶振的应用十分广泛。在一些需要时钟同步的系统中，如串行通讯协议等，芯片附近需要使用晶振来提供准确的时钟信号，确保设备正常工作。

In addition, the size of the crystal becomes smaller and the working voltage gradually decreases, making it more and more likely to be integrated inside the chip. Therefore, modern chips often integrate crystal circuits inside the chip.

此外，晶振的尺寸变小，工作电压也逐渐降低，使得它越来越容易被集成在芯片内部，因此现代芯片也常常在芯片内部集成了晶振电路。

When IC runs, when various micro-components work, it must be divided into order. Both crystal and ICs are connected through the PCB board copper wire. PCB is like a road. The car is running current or voltage, and the traffic lights are safe and safe. The function of the traffic lights is like crystal. Why is there always a crystal figure next to the IC? It is because the crystal is allocated to allocate the time distribution of the work order of each component, so that IC work normally.

IC在运行中，各微型元器件工作时，肯定要分先后顺序。晶振和IC都是通过PCB板铜线相连的，PCB就像是马路一样，汽车都是运行的电流或者电压，而红绿灯就是指挥交流安全的，红绿灯工作职能就像晶振一样。为什么IC旁边总有晶振的身影？是因为晶振要提供各部件先后工作顺序的时间分配，从而让IC正常的工作起来。

So, a crystal oscillator is like a ‘pacemaker’, it generates a fixed frequency of electronic pulses, which are provided to the chip to run at this rhythm.

所以，晶振，就好比“心脏起搏器”，它产生固定频率的电子脉冲，提供给芯片，让芯片按照这个节奏运行。
