Determine the MTBF of the synchronizer in Figure, assuming an asynchronous transition rate of 4 MHz and a clock frequency of 40 MHz, which is less than the maximum determined in Figure. In this situation, “synchronizer failure” really occurs only if DSYNCIN is metastable. In other words, SYNCIN may be allowed to be metastable for a short time, as long as it doesn’t affect DSYNCIN. This yields a better MTBF.
