I know how to use a 2 DFF edge detector to detect pulse from a slow clock domain to a fast one. Can anyone tell me another version of the edge detector that can do the fast-to-slow?
I thought I would stretch the pulse for 5-10 cycles if the clock frequecy between the two are 5-10 times different. But someone says this is not necessary and this guy gives me a simple answer that can detect the signal from 200MHz domain to a 1K domain, unfortunately I dont understand his design. Does anyone know the decent answer to the problem?
