Systems and method for transfering digital data and transfering parallel digital data in a serial data stream including clock information
The present invention provides a data transfer system including a data transmitter and a data receiver. The data transmitter converts a plurality of bits of transmission parallel data into serial data and generates a multi-level logic signal representing a plurality of bits of information in one symbol, the information being obtained by combining the serial data with a word clock as one-bit information. The word clock indicates a word delimiter in the serial data. The data receiver receives the transmitted multi-level logic signal, extracts the serial data and the word clock from the signal, and reproduces the parallel data based on the extracted word clock. In the data transfer system, a multi-bit digital signal can be transmitted as one signal including a word clock. Thus, components and mounting space to be allocated to transfer can be reduced.
