摘要： An input/output (IO) interface includes a data encoder which encodes each of a plurality of pieces of parallel data having different timings and generates a plurality of pieces of encoded data, and an alternating current (AC) coupling transmission unit which transmits the plurality of encoded data in an AC coupling method. The data encoder compares first parallel data with second parallel data from among the plurality of pieces of parallel data on a bit-by-bit basis and obtains the number of bits whose logic states have transited between the first parallel data and the second parallel data. When the number of bits whose logic states have transited is greater than or equal to a reference number of bits, the data encoder inverts bit values of the second parallel data to generate the encoded data. When the number of bits whose logic states have transited is less than the reference number of bits, the data encoder maintains the bit values of the second parallel data to generate the encoded data.
