1Wo-Register Synchronizer Without Delay: The price of delay lines has gone way up. Accordingly your friend Ben Bit diddle suggests building a two-register synchronizer (Figure 10-10) without any delay line by clocking one register with each edge of the clock as shown in Figure 10-51. What does this change do to the average delay of the synchronizer? For what range of phases should the phase comparator select the top flip-flop? How might you build the phase comparator without using a delay line?
