Abstract (en)
[origin: WO2008037944A2] An apparatus (100) for de-serialisation of a framed data stream, each frame being M-bits long and comprising a fixed frame alignment word, said apparatus comprising one first-order K:1 down-converter (102), K second-order L:1 down-converters (104-110), each connected to one of the outputs of the first-order down-converter and K slice aligners (112-118), each connected to outputs of the second-order down-converters (104-110). The apparatus further comprises a combiner (120) for combining all data streams from the slice aligners (112-118) into one data stream of width of K·L bits, wherein M is divisible by K·L and said first-order down converter (102) is adapted to form K different alignment slices from the frame alignment word by taking every K<SUP>th</SUP> bit of said frame alignment word, wherein each of the slice aligners searches for one of the K alignment slices in the received data stream and generates a marker indicating a bit sequence in the data stream that matches the sought alignment slice. The combiner (120) assembles the contiguous K·L bit wide data stream if within two adjacent clock cycles all K slice aligners generate said markers for K different alignment slices.
