Hi members,
A reset signal operating at 15MHz has to cross another clock domain 250MHZ. I have to use a synchronizer for CDC in order to avoid Metastability. I used for that the tree DFF synchronizer shown in this figure.
Will it be safe or It's better to use additional DFF to improve safety ?
How to decide the number of flops in that case ?
Thanks in advance.
