A system and method that detects a repetitive word, called a Sync Word, from a continuous bit stream is disclosed. In an acquisition mode, counters are used for detecting a Sync Word, which can be up to 64 bits in length. When the Sync Word has been detected for a fixed consecutive number of times, the system switches t o a tracking mode in which data from the bit stream is output. The Sync Word can be one o f two types of markers, and in combination can appear as a specific pattern. The Sync Word and pattern of Sync Words to be detected in the bit stream, are programmable .
