摘要： A transmitting circuit includes a positive differential node, a negative differential node, a voltage mode driver, and a current mode driver. The voltage mode driver generates a first positive differential signal and a first negative differential signal. The voltage mode driver provides the first positive differential signal to the positive differential node and provides the first negative differential signal to the negative differential node. The current mode driver generates a second positive differential signal and a second negative differential signal. The current mode driver provides the second positive differential signal to the positive differential node and provides the second negative differential signal to the negative differential node. A differential signal voltage swing width between the positive differential node and the negative differential node is based at least on the operational state of the current mode driver and/or the voltage mode driver.
