Can I use 2 Flop synchronizer to migrate a pulse from one clock domain to another provided that clocks phase shifted but of same frequency?
The issue is how much they're out of phase. If the data can change during the FF's setup and hold times you have a metastability problem and need to use 2 FFs: the second will be clocked when any ringing on the first is over. Otherwise 1 will suffice. PW limits are based on the same consideration.
