利用扩频技术减少高速时钟电路的电磁干扰

数字电子设备的运行速度越来越快,其时钟频率就越来越高,时钟电路产生的辐射干扰就越为严重。本文介绍了一种对抑制时钟电路辐射干扰较为有效的方法-时钟扩频技术。

Optimize the EMI of High-speed Clocking Circuit by Utilizing Spread Spectrum Technique

We know that when the digital electronics equipment operates with higher speed, then it's clocking frequency would get much higher, then the radiated disturbance produced from the clocking circuit would become more serious. The paper introduces an effective method Spread spectrum clocking technique, which can overcome the radiated disturbance produced from the clocking circuit.
