Abstract:
1. A data handover unit for transferring data from a first clock domain to a second clock domain, comprising: a first clock unit for supplying a first clock signal; a selector stage for sampling an incoming data stream with regard to the first clock signal; a second clock unit for supplying a second clock signal; a storage unit coupled with the selector stage, wherein the storage unit has a first plurality of storage elements, each of which is configured to store one bit of data of the sampled data stream; and an output unit for parallelly reading out a frame of data from a second plurality of storage elements within the first plurality of the storage elements with respect to the second clock signal, wherein the selector stage is configured to successively write the data bits of the sampled data stream into the first plurality of storage elements and wherein the respective data bits of the sampled data stream are stored in the respective storage elements at least until read out by the output unit.
