Abstract
A method for locating a synchronization sequence S having a length s in a serial bit stream, and an arrangement for the implementation of such a method make use of the fact that the synchronization sequence S is composed of a plurality of individual words A, B, C having respective lengths a, b, c. The search in the serial bit stream relates only to a word length a, b, c and not to the entire length s of the synchronization sequence S. When a word A, B, C has been recognized, the expected value for the search for the next word A, B, C is set by a controller. The expected values for the words A, B, C to be searched are programmable and thus can be freely defined for each application, so they can be selected in an application-specific manner. The words A, B, C to be searched can be characterized by two auxiliary bits Z whose formation is exactly inverted relative to that of normal data words A, B, C. This guarantees an unambiguous and dependable recognition of these words A, B, C.
