  • Patent number: 9521345
    Abstract: A data transmission circuit includes a data output unit (DOU) connected to a positive data transmission line and a negative data transmission line. The DOU generates a recovered data signal based on data signals communicated via the positive and negative data transmission lines. Data signal driving units are respectively connected at different points along the positive and negative data transmission lines, where each data signal driving unit generates and provides a positive data signal and a negative data signal based on a data input signal and a data transmission distance between the data signal driving unit and the data output unit.
