    摘要: A serial-parallel conversion circuit provided on one end of a cable body converts a first serial signal into parallel signals and outputs the parallel signals to parallel signal lines. A parallel-serial conversion circuit provided on another end of the cable body converts the parallel signals inputted from the parallel signal lines into a second serial signal and outputs the second serial signal to outside.

    摘要: To aim to provide an interface circuit that supports both a single-ended method and a differential method as a transmission method, and one of pairs of input terminals for a differential signal is shared to input/output a single-ended signal.A differential signal receiving circuit that receives a differential signal input through the pair of shared terminals is activated when a differential signal is input to a pair of dedicated input terminals for a differential signal, which is different from the pair of shared terminals. After the differential signal receiving circuit is activated, the active state is maintained by a built-in controller.Accordingly, the activation of the differential signal receiving circuit that receives a differential signal input through the shared terminals is controlled by controlling the differential signal input through the pair of dedicated input terminals, and furthermore, the possibility that the differential signal receiving circuit becomes inactive at an unexpected timing is reduced to a low level.

    摘要: In a communications system for differential signals, a driver circuit is connected to a receiver circuit by a pair of differential signal lines. When data is not being transmitted, the differential signal lines are maintained at a predetermined electric potential, and when data is to be transferred, a differential signal is output at predetermined electric potentials. The receiver circuit switches between a power-down state and a normal state when detecting states of the electric potentials of the differential signal lines.
