Introduction to the application fields of crystal oscillator frequency [Copy link]

Crystal oscillator is a frequency component, and different frequencies are used in different products. Crystal oscillators are used in 80% to 90 % of electronic products, and are widely used. How much do you know about the crystal oscillator frequency? Do you know which products the crystal oscillator frequency is used in? Let's share with you the different requirements of different products for the crystal oscillator frequency.
