Any discussion of clock domain crossing (CDC) should start with a basic understanding of metastability and synchronization. In layman’s terms, metastability refers to an unstable intermediate state, where the slightest disturbance will cause a resolution to a stable state. When applied to flip-flops in … Vedeți mai multe A synchronizer is a circuit whose purpose is to minimize the probability of a synchronization failure. We want the metastability to resolve within a synchronization period (a period of the destination … Vedeți mai multe The easy case is passing signals from a slow clock domain to a fast clock domain. This is generally not a problem as long as the faster clock is > 1.5x frequency of the slow clock. … Vedeți mai multe Even though we would all like to live in a purely synchronous world, in real world applications you will undoubtedly run into designs that require multiple asynchronous … Vedeți mai multe The more difficult case is, of course, passing a fast signal into a slow clock domain.
