Summary: | A controller arrangement and method for effectuating data transfer between a first clock domain and a second clock domain. In one embodiment, inversion circuitry inverts a first clock signal associated with the first clock domain into an inverted first clock signal that is used in effectuating a SYNC pulse during coincident edges of the inverted first clock signal and a second clock signal associated with the second clock domain. Clock synchronizer controller circuitry operates responsive to sampled sync pulses based on the SYNC pulse to generate domain synchronizer control signals for effectuating data transfer between the first and second clock domains. |
