摘　　要：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。We know that when the digital electronics equipment Operates with higher speed, then it＇s clocking frequency would get m＇uch higher, then the radiated disturbance produced from the clocking circu^t 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.

关 键 词：电磁兼容 辐射干扰 高速时钟电路 时钟扩频技术
