A data receiving apparatus of a PCI Express system includes a receiving device, an 8B10B decoder, a forged packet removing device, and a descrambling circuit. The forged packet removing device determines whether a disparity error occurs; and an offset removing circuit compensates a number of cycles of the lane offset. The data receiving apparatus is capable of eliminating error packet caused by framing error and preventing the problem of symbol disorder and disconnection caused by set ordered noise. Furthermore, the data receiving apparatus is also capable of removing offset.
