A data cable, electronic system and method for transmitting MIPI signals are provided. The electronic system includes a first electronic device configured to generate at least one pair of MIPI (Mobile Industry Processor Interface) differential signals, and a data cable and a second electronic device connected to the first electronic device via the data cable. The data cable is configured to receive the at least one pair of MIPI differential signals from the first electronic device, and perform impedance matching and shielded grounding processing on the at least one pair of MIPI differential signals, and transmit the processed at least one pair of MIPI differential signals to the second electronic device.
