摘要： An inter-line switching element formed of a MOSFET is provided between a pair of signal lines. When the level of a differential signal changes from high to low, a control circuit turns on the FET for a fixed period thereby to suppress ringing by decreasing the impedance between the signal lines when the level of the differential signal transitions, and causing the energy of the distortion of the differential signal waveform to be absorbed by the on-resistance of the FET.

摘要： A transmission apparatus for differential communication includes a driver bridge circuit and a pair of noise protection circuits. The driver bridge circuit includes four output devices that are independently connected between each of a pair of transmission lines and a power line or a ground line. Each noise protection circuit is provided to a corresponding transmission lines. Each noise protection circuit includes a ground potential detector and an impedance controller. The ground potential detector detects a potential of the corresponding transmission line with respect to the ground line. The impedance controller causes an impedance of the corresponding transmission line with respect to the ground line to become equal to an impedance of the other transmission line with respect to the ground line, when the detected potential becomes outside a predetermined potential range.

摘要： When a transmission signal is detected as having been changed from a high level to a low level, two transmission lines are connected for only a predetermined time through a diode by a first transistor and a second transistor. The diode is arranged such that its forward direction is from a high-side transmission line to a low-side transmission line. The diode turns on, when a potential of the high-side transmission line becomes higher than that of the low-side transmission line by ringing and a potential difference therebetween exceeds a forward drop voltage of the diode. As a result, a peak wave level of a positive side in the ringing is limited to the forward drop voltage of the diode.

摘要： The communication signal generating device is for use in a communication system where communication signals each of which is set at a first level or a second level are exchanged among a plurality of communication apparatuses through a communication line. The communication signal generating device includes a switching element provided in a communication line to connect the communication line to a ground or a constant voltage source, and a driving means to generate a first communication signal at the first level by turning on the switching element to thereby pass a certain current to the communication line, and generate a second communication signal at the second level by turning off the switching element to thereby pass no current to the communication line. The driving means is configured to gradually increase an output impedance of the switching element during one bit time of the first communication signal.

摘要： In a communication system, plural nodes are communicably connected to a communication line and mutually communicate based on an NRZ (Non Return to Zero) code. Each node detects, as a data frame head, a dominant level when a signal on the line changes to a dominant level during a stand-by state of the line. An activation frame is transmitted during a sleep mode. The activation frame has an activation pattern area storing therein a bit pattern showing that the frame is the activation frame, a specific pattern area storing therein a bit pattern showing a node to be activated, a boundary position satisfying a predetermined boundary condition and being a boundary between the activation and specific pattern areas. Each node performs a switchover from the sleep mode to a normal mode based on the bit patterns in the activation and specific pattern areas and information given by the boundary position.
