Abstract
A synchronization system synchronizes a first signal with a second signal. Data values of the first signal are stored in a first-in, first-out (FIFO) device in response to strobe signals that latch the first signal. The output of the FIFO device is clocked by clocks of the second signal. Therefore, the signal output by the FIFO device is synchronized with respect to the second signal. If the frequencies of the first signal and the second signal differ, then multiple FIFO devices are used to successively store the data of the first signal. In this regard, the signal output by the plurality FIFO devices has the same frequency as the second signal and has a bit length larger than the first signal.
