Techniques to make clock switching glitch free 时钟无毛刺切换技术,glitch 毛刺,glitch free 无毛刺 随着越来越多的多时钟应用于当今的芯片中(尤其是在通信领域),在芯片运行时经常需要切换时钟源。通常的实现方式是:在硬件中复用两个不同频率的时钟源,并通过内部逻辑控制复用器 MUX。 这两个时钟在频率上可能完全...

在时钟的下降沿寄存选择信号(SELECT)可确保在任一时钟处于高电平时输出端不会发生变化,从而防止斩波输出时钟(意思是下降沿寄存,可以保证下降沿到来之前输出端保持不变,这样就不会斩断当前时钟了)。 从一个时钟的选择到另一个时钟的反馈使开关能够在开始传播下一个时钟之前等待取消选择当前时钟,从而避免任何毛刺(意思是...

Figure 1 — Clock switching multiplexer (MUX) Glitch Free clock switching for related clock sources A solution to prevent glitch at the output of a clock switch where source clocks are multiples of each other is presented in Figure 2. A negative edge triggered D flip-flop is inserted in the...
if you register the 39MHz signal through two or more stages of 270MHz then that synchronises it to the fast domain glitch-free. Then you apply mux using 270MHz register before the pin on both signals; the synchronised slow and the fast signals. Translate 0 Kudos...
The hard part is ensuring the output is glitch free (long after the selection is made). I believe that I need an output register post-mux, but the register would need to have the clock switched between the two clock domains to function properly. Using a...
