Crossing from a slow to fast clock domain The slower clock is your source clock domain. The faster clock is your destination clock domain. In the faster clock domain, the first Flip-Flop has a metastable output.
WebAug 13, 2024 · This means when you assert a shift out, on that cycle, you retrieve the output data and the FIFO prepares the next word on the next clock.
