Abstract
An arrangement for transferring a data signal from a first clock domain (bus_slow) to a second clock domain (bus_fast) in a digital system. The first clock domain (bus_slow) has a first clock (ck slow) with a frequency less than a frequency of a second clock (ck fast) in the second clock domain (bus_fast). The arrangement is configured to transfer the data signal from the first clock domain (bus_slow) to the second clock domain (bus_fast), detect whether a predetermined transition occurs in the first clock (ck slow) within a predetermined period of time, using detecting means () clocked by the second clock (ck fast), and transfer the data signal from the first clock domain (bus_slow) to the second clock domain (bus_fast) again if the detecting means () detects the predetermined transition in the first clock (ck slow) within the predetermined period of time.
