Abstract:
An electronic apparatus for transmitting serial data through first and second signal lines in which a transformer is inserted, wherein first and second terminals on a primary side of the transformer are respectively connected to the first and second signal lines, comprising:a first differential output buffer whose positive and negative output terminals are respectively connected to the first and second signal lines; and a second differential output buffer whose positive and negative output terminals are respectively connected to the first and second signal lines, wherein the first and second signal lines are driven by using said first and second differential output buffers to convert each binary data constituting serial data into ternary data including a first state in which a current flows in said transformer in a positive direction, a second state in which a current flows in said transformer in a negative direction, and a third state in which no current flows in said transformer, and the ternary data is output onto the signal line pair.
