摘　　要：在数字系统中各个模块所需的时钟频率往往各不相同，通常采用分频的方法由系统时钟得到所需频率。根据分频原理，基于SE120A芯片，提出了一种应用于核电子领域的2～64之间任意整数分频的实用电路，并对该电路进行了测试和分析，结果显示该分频电路基本无噪声，分频效果良好，稳定性好。Different components in a digital system often need different working frequencies, the way we often used is clock division from the system clock. Through the analysis of frequency divider principle, a applied integer frequency dividing circuit with SE120A is proposed. It can divide the frequency multiple from 2 to 64. It＇s usually used in nuclear electronics. It＇s testing and analysis is displayed that it has no noise,good frequency division effect and stability.
