A low voltage differential signaling generating circuit, which comprises a current source a pair of output nodes for providing a differential signal by virtue of a voltage difference therebetween, first and second differential switch circuitries and a bypass circuitry. The first differential switch circuitry selectively connects the current source to the first output node based on a control signal to cause a current flow from the first output node to the second one. The second differential switch circuitry selectively connects the current source to the second output node based on the control signal to cause a current flow from the second output node to the first one. The bypass circuitry is arranged in parallel to the first and second differential switch circuitries and is selectively switched based on an idle mode signal to prevent a current between the output nodes.
