Description

technical field [0001] The invention relates to a configurable high-speed LVDS driver with a short-circuit self-protection function, belonging to the technical field of high-speed data interfaces. Background technique [0002] The data transmission rate of military electronic equipment such as broadband communication, radar navigation, and electronic countermeasures continues to increase, and higher requirements are placed on high-speed data transmission interfaces. LVDS interfaces are widely used due to their advantages such as high speed, low power consumption, and low noise. The LVDS interface output driver realizes the output of the high-speed signal generated by the circuit to the channel, and realizes the high-quality transmission of the high-speed signal. The output common mode level, output impedance, and output signal amplitude of the driver circuit directly affect the quality of the driver output signal, and the requirements for the driver are also different for di...
