摘要:
A data transmission system is provided in which it is possible to perform both of suppressing the degrading of the slew rate and suppressing the ringing even if load capacitance of an input buffer is changed.The data transmission system transmitting data from an output buffer to the input buffer through a trace is provided with first RC parallel circuits connected in series to the trace on a first Printed Circuit Board (PCB) on which the output buffer is mounted, and second RC parallel circuits connected in series to the trace on a second Printed Circuit Board (PCB) on which the input buffer is mounted, and which can be connected and separated to and from the first Printed Circuit Board (PCB).

To suppress power consumption and enhance signal quality as compared with the case where first and second semiconductor elements are terminated only by on-chip input termination resistor circuits. A first semiconductor element with a switching function and a second semiconductor element with a switching function are connected to each other with a substrate interconnection, and a resistor element is connected in parallel with the substrate interconnection. The resistor element is placed at an arbitrary position or a branch point on the signal interconnection.

The present invention maintains plugging-unplugging durability of connector pins for connecting to a signal wiring board, as well as reduces a stub length of a through hole connecting to a signal wiring. In the signal wiring board according to the present invention, a through hole connecting to the inner-layer signal wiring is formed to be shorter than the other through holes. A through hole in which a connector pin connecting to the inner-layer signal wiring is inserted is formed to have a length corresponding to a depth of the inner-layer signal wiring.

摘要:
An electronic circuit device having a power wiring resonance inhibition function includes a plurality of electronic circuit elements, and a wiring board having the electronic circuit elements disposed thereon. The wiring board includes a plurality of planar power supply wires for supplying power to the electronic circuit elements. The planar power wires include a pair of planar power supply wires for supplying power to the electronic circuit elements at a predetermined voltage. The electronic circuit device also includes a plurality of damping elements disposed at a plurality of positions on the wiring board. The damping elements are connected between the pair of planar power supply wires at a plurality of positions on the pair of planar power supply wires. The damping elements reduce power supply system impedance and inhibit power wiring system resonance, thereby reducing supply voltage fluctuation caused by the power wiring system resonance and noise caused by the supply voltage fluctuation.
