A data receiver identifies an alignment symbol in a parallel data stream including encoded symbols, generates a bit order indicator indicating a bit order of the alignment symbol identified in the parallel data stream, and generates a symbol stream including the encoded symbols. Further, the data receiver decodes symbols in the symbol stream and generates a bit polarity indicator indicating a bit polarity of the parallel data stream based on the decoded symbols. Additionally, the data receiver generates a formatted symbol stream having a predetermined bit order and a predetermined bit polarity, based on the symbol stream, the bit order indicator, and the bit polarity indicator. In some embodiments, the data receives a serial data stream and generates the parallel data stream by deserializing data in the serial data stream.
