Abstract
An I/O device comprises a driving unit coupled between a first voltage and a second voltage, and configured to receive a first signal so as to drive a second signal for swing with a second swing range narrower than a first swing range between the first voltage and the second voltage and supply the second signal to a transmission line. The driving unit includes a first stabilizer coupled between the first voltage and the transmission line and a second stabilizer coupled between the second voltage and the transmission line.
Claims14
An input and output (I/0) device, comprising:
- a driving unit coupled between a first voltage and a second voltage, and configured to receive a first signal to drive a second signal to swing with a second swing range narrower than a first swing range where the first swing range is between the first voltage and the second voltage, and the driving unit is configured to supply the second signal to a transmission line, the driving unit including a first stabilizer coupled between the first voltage and the transmission line and a second stabilizer coupled between the second voltage and the transmission line;
- and
- a receiver coupled between the first voltage and the second voltage, and configured to receive the second signal through the transmission line to output a third signal, the receiver including a third stabilizer coupled between the first voltage and the transmission line and a fourth stabilizer coupled between the second voltage and the transmission line,
- wherein the receiver matches a middle point of the third signal and that of the second signal by adjusting the third signal to swing the second swing range.

An I/O system, comprising:
- a driving unit configured to receive a data signal that falls within a first swing range, narrow the first swing range by including voltage lowering elements, and supply a transmission data signal that falls within a second swing range through a transmission line;
- a receiver configured to receive the transmission data signal as a reception data signal, adjust a swing range so that the reception data signal has the same second swing range as that of the transmission data signal, and match a middle point of the reception data signal and that of the data signal;
- a level shifter configured to adjust a voltage level so that the second swing range has the first swing range so as to supply a data output signal;
- and
- a final driving circuit configured to receive a data output signal having the adjusted voltage level.
