A circuit for end-of-burst detection in a portion of a received bit stream is disclosed. The circuit comprises: a first counter for counting the number of bits in the portion, a second counter for counting the number of bit value transitions in the portion, and a circuit for comparing the counted number of bits in the portion and the counted number of bit value transitions therein with preset values, the circuit for comparing is further arranged for generating a signal indicative of end-of-burst detection based on the result of the comparison.
