Patent ID: 7924055

Claim:
A data transmitting system comprising: a transmitter that suppresses coupling noise, the transmitter configured to operate according to a differential voltage driving scheme during data transmission of logic signals and operate according to a common voltage driving scheme by equalizing the potential of a pair of transmission lines during a transition interval of the logic signals, wherein the transmitter comprises: a pre-driver that full-swings logic signals input to the transmitter by performing buffer function; a transistor circuit that levels-down the logic signals transmitted from the pre-driver into small signals and is operated as a MOS transistor switch to provide the leveled-down logic signals as high/low; a switch circuit for shorting and opening the pair of transmission lines, wherein the pair of transmission lines are connected to the transistor circuit; and an edge masking circuit that generates control signals for the switch circuit by using the logic signals processed in the pre-driver, wherein the control signals short the pair of transmission lines during the transition interval of the logic signals; and a receiver connected to the transmitter through the pair of transmission lines, wherein the receiver recovers data by sensing a voltage difference in signals from the pair of transmission lines.
