Claim:
1. A system for identifying a point in time of receipt of a data packet having a predetermined part, the system comprising: a de-serializer for: receiving serial data from a serial data path, deriving a first clock signal with a first frequency from the serial data path and deriving a second clock signal with a second frequency, the second frequency being the first frequency divided by a predetermined integer, outputting parallel data to a parallel data bus having a predetermined number of parallel data paths, the parallel data relating to the serial data, and the parallel data being output in accordance with the second clock signal, an identifier for identifying one of the parallel data paths in which at least a portion of the predetermined part is output, a timing device for estimating the point in time from the identified one of the parallel data paths and the second clock signal, wherein a scheme is known for controlling on which of the parallel data paths, data is outputted, then the second clock signal for outputting the predetermined part and the identified one of the parallel data paths are used to calculate the point in time of the first clock signal for receiving the predetermined part of the data packet in the serial data path.
