PCB for stabilizing clock signals and wiring method for PCB

Abstract

The invention discloses a PCB for stabilizing clock signals. The PCB is provided with a processor, a crystal oscillator, a first signal line and a second signal line. The processor comprises a first pin and a second pin. The crystal oscillator comprises a first base pin and a second base pin. The first pin is connected with the first base pin through the first signal line, and the second pin is connected with the second base pin through the second signal line. The length of the first signal line is equal to that of the second signal line. The first signal line and the second signal line are arranged in an arc shape. The invention further discloses a wiring method for the PCB for stabilizing the clock signals. The processor and the crystal oscillator are reasonably wired on the PCB so that the clock signals cannot be interfered, and therefore the frequency of the clock signals is stabilized, and the program running stability of electronic equipment is achieved.

Description

technical field [0001] The invention relates to the field of PCB wiring, in particular to a PCB with a stable clock signal and a wiring method thereof. Background technique [0002] With the development of science and technology, electronic equipment has gradually become popular and entered thousands of households. As long as there is a processor in the electronic equipment, the processor must be provided with a clock signal by the crystal oscillator before the processor can work normally. At present, when designing the PCB (Printed Circuit Board: Printed Circuit Board) of electronic equipment with a processor, the wiring of the crystal oscillator is often not taken seriously, and it is considered complete only after it is passed through, leaving hidden dangers, especially In high-frequency circuits, sloppy crystal oscillator wiring will cause the frequency of the clock signal to tremble, resulting in product instability. For example: the clock signal provided by the crystal...

At present, when designing the PCB (Printed Circuit Board: Printed Circuit Board) of electronic equipment with a processor, the wiring of the crystal oscillator is often not taken seriously, and it is considered complete only after it is passed through, leaving hidden dangers, especially In high-frequency circuits, sloppy crystal oscillator wiring will cause the frequency of the clock signal to tremble, resulting in product instability. For example: the clock signal provided by the crystal oscillator is easily interfered by other signals, and it fails in the electromagnetic interference experiment; or When debugging, the program runs correctly, but when it is working normally, the program runs incorrectly; even restarts, timing errors or crashes occur for unknown reasons
