Abstract
A synchronizer for providing a source-synchronized clock bus reduces the effect of clock skew during the signal capturing process. The synchronizer includes at least one capture latch in the capture clock domain for capturing the signal, at least one storage latch for storing the signal coupled to the at least one capture latch, and a multiplexer coupled to the at least one storage latch. The multiplexer synchronizes data transfer of the at least one storage latch and the at least one capture latch, and an internal latch in the internal clock domain. The signal is controlled and processed by strobe signals and clock signals from the sending chip.
