<p>A chip (110, 120, 130) applied to a serial transmission system includes an input terminal, a core circuit (114, 1 24, 1 34), an output terminal, a first transmission line, a second transmission line and a spare transmission line, where the input terminal is used to receive an input signal from a source outside the chip (110, 120, 130), the output terminal is used to output an output signal, the first transmission lines is coupled between the input terminal and the core circuit (114, 124, 134), the second transmission line is coupled between the core circuit (114, 124, 1 344) and the output terminal, and the spare transmission line is coupled between the input terminal and the output terminal. When the core circuit (114, 124, 1 34) cannot process the input terminal normally, the input signal is directly transmitted to the output terminal via the spare transmission line, and the input signal serves as the output signal to be outputted from the output terminal.</p> |
