Abstract:
1. A low voltage differential signal driving circuit, comprising: a positive differential output terminal and a negative differential output terminal, providing a differential output signal and coupled to a transmission interface; and a transition accelerator, comprising: a first transition acceleration switch, turned on according to a first control signal to connect a high voltage source to the positive differential output terminal; a second transition acceleration switch, turned on according to an inversed signal of the first control signal to connect a low voltage source to the negative differential output terminal; a third transition acceleration switch, turned on according to a second control signal to connect the high voltage source to the negative differential output terminal; a fourth transition acceleration switch, turned on according to an inversed signal of the second control signal to connect the low voltage source to the positive differential output terminal, wherein: the first control signal is enabled to turn on the first and second transition acceleration switches in accordance with the transmission interface when the differential output signal transits from low to high; and the second control signal is enabled to turn on the third and fourth transition acceleration switches in accordance with the transmission interface when the differential output signal transits from high to low.
