Dear all, Is there a potential problem possible when you have a lot of high speed digital IC's in parallel on the same voltage supply track and you use low ESR decoupling caps? What can happen when you do that? Does any one has some reference documentation about decoupling of high speed IC's? Are there rules of thumb to follow for decoupling? Any information is more then welcom! Many thanks in advanced.
