Abstract
The invention relates to a data reception device for receiving packetized data in the form of a differential signal. This device comprises a data reception section that generates a digital signal an the basis of the differential signal; a decode section that generates a bit synchronization signal and serial binary data based on this digital signal; a link detection section that detects whether or not a link has been guaranteed, based on this digital signal, and outputs a link signal; and a polarity determination section that determines whether polarities have been identified correctly, based on this serial binary data, the bit synchronization signal, and the link signal. The polarity determination section determines that the polarities have been determined incorrectly when at least one of the following conditions is satisfied: the first consecutive pair of identical bits within each of n packets of data received in succession is detected to be 00, and it has been detected that the link has not been guaranteed for a specific period of time. When the polarities have been identified incorrectly, a polarity correction section of the data reception section corrects them.
