Abstract
A circuit for buffering data is disclosed. The circuit comprises a first circuit which is coupled to receive a stream of data blocks using a first clock signal. The first circuit removes data blocks, such as idle data blocks or a sequence ordered set of a pair of consecutive sequence ordered sets, from the stream of data blocks to create a first modified data stream which is coupled to a memory device. Finally, a second circuit coupled to the memory device generates a second modified data stream using a second clock signal. The second modified data stream preferably comprises the data blocks of the first modified data stream and idle data blocks inserted among the data blocks of the first modified data stream. Methods of buffering data received in a first clock domain and output in a second clock domain are also disclosed.
