  • USB chip and operation method thereof
    Patent number: 12038863
    Abstract: A USB chip includes positive and negative data pins, first and second transceiver circuits, a switching circuit, and a control circuit. During a high-speed handshake stage, the control circuit controls the switching circuit to be in a second state to disconnect the positive and negative data pins from a first terminal impedance circuit and actuates the second transceiver circuit to transmit a second voltage signal via the positive and negative data pins alternately. During a high-speed transmission stage, the control circuit controls the switching circuit to be in a first state to connect the positive and negative data pins with the first terminal impedance circuit and actuates the first transceiver circuit to transmit a first voltage signal, which has a first voltage level lower than a voltage level of the second voltage signal, via the positive and negative data pins alternately.
