Taktsignalübertragung über einen asynchronen Datenkanal

摘要

An input clock signal associated with an input data signal is divided by a predetermined integer N, to form a sub-rate clock signal. The sub-rate clock signal is sampled and transmitted along with the input data over an asynchronous data channel. At the receiver, the resulting sub-rate clock signal is received and coupled to a phase lock loop which generates a recovered clock signal of the same frequency and substantially in phase with the input clock signal. <IMAGE>
