<p>An apparatus for decoding a serial datastream of channel words into a datastream of information words is provided. The apparatus comprises an input terminal (10) for receiving the serial data stream of channel words, a serial-parallel converter unit (16) means for serial-to-parallel conversion of the serial datastream into a parallel datastream of n-bit intermediate channel words. Further, a clock signal generation unit (14) is present for deriving a first clock signal of a specific frequency from the serial datastream of channel words. A frequency division unit (18) is present for dividing the frequency of the clock signal generated by the generation means by a factor of n, so as to obtain a second clock signal of a reduced frequency. A sync word detection unit (24) is available for detecting sync words present in said serial datastream of channel words.</p> |
