ABSTRACT:
A method and apparatus for guaranteeing clock edge synchronization is disclosed. In one embodiment, a system for synchronizing clock signals includes a clock unit and a synchronization unit. Both the clock unit and the synchronization unit may be configured to receive a reference clock signal. The clock unit may be configured to drive a plurality of domain clock signals to various clock domains. The synchronization unit may be configured to assert a synchronization pulse once every N reference clock cycles. Clock edges of the domain clock signals may be aligned with each other responsive to asserting the synchronization pulse.
