摘要:
It is an object of the invention to inhibit a drop in the data transmission efficiency due to the transmission of an interrupt signal. The invention provides a signal transmission method that is characterized in that a reception side and a transmission side partition data into a plurality of data fragments and send and receive the plurality of data fragments over at least two transmission lines, in that the transmission side transmits first data fragments of the plurality of data fragments over a first transmission line of the transmission lines, transmits data packets that include header information, a second data fragment that has the same bit length as the first data fragments, and footer information over a second transmission line other than the first transmission line, and transmits the first data fragments and the second data fragments in synchronization, and in that an interrupt signal for controlling the transmission side is transmitted from the reception side to the transmission side in a time slot that is an interval between first data fragments that are adjacent on the first transmission line.

An IC package (50) includes an integrated circuit (10) for transmitting and receiving a pair of differential signals composed of a signal having positive polarity and a signal having negative polarity, a first signal terminal (41a) for transmitting the signal having positive polarity, a second signal terminal (41b) for transmitting the signal having negative polarity, and a third terminal (43) arranged between the first signal terminal and the second signal terminal. The first and second terminals are electrically connected to the integrated circuit, and the third terminal (43) is not electrically connected to the integrated circuit.
摘要:
A flexible cable is provided in which a transmission characteristic can be ensured in a high frequency band, and electromagnetic noises can be suppressed. A flexible cable 11 includes a sheet-like base member (dielectric substance) 1; an adhesive (dielectric substance) 2 which bonds the base member 1 to a cover member (dielectric substance) 3; a shield member 4 which covers the cover member 3 and is bonded or printed to the cover member 3 to suppress electromagnetic noises to be radiated; and a top coating member 5 which covers the shield member 4 to protect the shield member 4. The flexible cable 11 has a differential signal wire group 7 including differential signal wires 6 through which differential signals pass and guard ground wires 9a which prevent the interference from other differential signals; a low-speed signal wire 8 through which a low-speed signal passes; a ground wire 9 used as a ground; and a shield ground wire 10 which is adapted to allow the electric potential of the shield member 4 to be identical to the electric potential of the ground, all of which are provided in the adhesive 2. The differential signal wires 6 are not covered with the shield member 4.
