Flip flop synchronizer
WebSo, as you suggest, maybe there are other multi-flip-flop (N-FF) synchronizers to be found there. Specifically, as you say, when ISERDES is configured in MEMORY mode with CLKDIV=OCLK=CLK then Fig 3-5, UG471(v1.10) shows apparent 3-FF and 4-FF synchronizers: D > FF0 > FF2 > FF7 > Q2; WebAug 15, 2024 · The reason to add a reset would be so that the flip-flops can be either set or cleared when a reset signal is applied. I can think of plenty of cases where this would not be necessary, and some where it would. For one example, what if the destination clock is not running? An async reset would be able to force a safe state. Last edited: Aug 14, 2024
