Common Frequency of Quartz Crystal Application

At present, there is a special standard for the systems using crystal oscillators, especially for the frequency. In addition, other specifications like frequency stability and tolerance should be confirmed according to the actual occasions.

In the field of consumer electronics, such as:

24MHZ mostly be application in the smart phone

13.560MHZ/27.120MHZ on NFC

21.4MHZ/ 21.7MHZ intercom

14.318MHZ/ 32.768kHz application on computer motherboard

24.576MHZ sound card crystal oscillator

25MHZ network card crystal oscillator, etc..

For smart home system, 

32.768kHz/4.000MHZ/4.9152MHZ will be used on air condition

13.5MHZ/27MHZ/54MHZ will be used on Set top box

In addition,

12.000MHZ/21.4MHZ/18.9375MHZ/19.069928MHZ/28.375MHZ/28.63636MHZ/37.875MHZ/13.560MHZ/24MHZ/12.270MHZ could be applied the security system

12MHZ/16MHZ/26MHZ/32.768kHz are used in network communications 

(the value of active crystal oscillator has been widely reflected and developed in the communication system. Many high performance crystal oscillators are mainly used in communication network, wireless data transmission and high-speed data transmission etc.)
