Design 61 50 MHz Clock 2 nsec Figure 4­4: Inconsistent Documentation For example, suppose you have a timing diagram that shows a 50 MHz or 20 nsec clock but the timing shows 50 MHz and 2 nsec, see Figure 4­4. There is no way of knowing which is correct, so do not assume. Instead, go back to the "source," not a coworker or friend, to get clarification and to clear up the inconsistencies.
