Abstract:
1. A data input port comprising: an input buffer for receiving a serial data stream and for outputting a parallel data stream comprising multiple bits of said serial data stream in parallel groups; a first detector unit for detecting a predetermined symbol in the data stream, and for outputting a positive detection status signal to the input buffer in response to a detection of said predetermined symbol; and a second detector unit for detecting data transitions in the serial data stream for generating a serial data clock signal and for generating a plurality of candidate clocks from the serial data clock signal, each candidate clock having the same frequency, the frequency being less than the frequency of the serial data clock signal; wherein the input buffer is operable to, upon reception of the positive detection status signal from the first detector unit, select a data ordering start position within the buffer for output of the parallel data stream and for outputting a clock selection signal for selecting between the plurality of candidate clocks on the basis of the selected data ordering start position.
