External circuit structure of CPU clock circuit

Clock oscillators are commonly used in digital signal processing circuits as well as microprocessor circuits ( microprocessors are also digital signal processing circuits).
The transmission and processing of digital signals require clock signals. It is the beat signal and time signal in the system, and it is also
the synchronization signal for identifying data signals. A common clock oscillator is a crystal oscillator.
 It is the structure of a circuit that provides clock signals for circuits in digital products. It is composed of quartz crystal Xl01 and three inverting amplifiers
(A, B, c in 7074).
