I am using a Zybo Z7-20 to collect video data which comes with its own clock. Meaning that it the video source has 8 parallel bits and a clock with which to sample them. My plan was to make the entire design synchronous to this external clock, but then someone told me that it can be problematic to use an external clock. Can anyone confirm this? I see that there are a lot of different kinds of clocks (bufg,bufio...) Can anyone give advice/tips/useful info on this?
