WebJul 6, 2013 · You are right but TCO_ext is not = TCO of external device rather it is just another name for it. The issue you raised is because some chips do not give you TCO but rather tSU/tH required at receiving device and then this translates to: TCO(max) = UI - tSU . TCO(min) = tH --- Quote End --- Thank you,kaz. WebMar 4, 2008 · 992. Re: setup and hold. this is because this are not tpd delay values. for tco you will have maximum tpd time which is important. however thold is imposed on the logic driving the part. i.e it has to have min. thold. time, the max is infinity. for setup it is also imposed on driving device, since it now have to support certein tmax tpd to ... hillsboro il ace hardware
