Abstract
A transmitter provides a duobinary signal corresponding to one of level 0, level 1, and level 2 based on first data and second data, and includes a pull-up driving circuit including a plurality of pull-up resistors selectively coupled between a first power source and a transmission node according to the first data and the second data; and a pull-down driving circuit including a plurality of pull-down resistors selectively coupled between the transmission node and a second power source, wherein at least one of the plurality of pull-up resistors is coupled between the first power source and the transmission node both when the first data is activated and when the second data is activated, or at least one of the plurality of pull-down resistors is coupled between the second power source and the transmission node both when the first data is activated and when the second data is activated.
