Step 1 of 2 8.18DP From the Table 8-43 in the textbook, the and of TI's estimates for the 74LS74 family is: = Write the formula for mean time between failures: For the first synchronizer the t,=80 ns and frequency is 10 MHz. If the asynchronous input change can occur on every clock tick then is substituted for the parameter a, then the synchronizer MTBF is: MTBF is about 3.6 million years between failures. Step 2 of 2 For the second synchronizer the ns and frequency is 16 MHz. If the asynchronous input change can occur on every clock tick then f is substituted for the parameter a, then the synchronizer MTBF is: =38.26 The synchronizer at 16 MHz is too lousy. Thus synchronizer at 10 MHz is recommended for the 74LS74 with TI's estimates.
