    摘要: An output circuit comprises an output transistor circuit for applying an output signal to a transmission line connected to an output terminal, a circuit for driving the output transistor circuit in response to an input signal applied to an input terminal, and a control circuit by which the signal amplitude of a first wave applicable to the transmission line with a load connected to the output terminal through the transmission line is rendered approximately one half of the output signal amplitude with a load directly connected to the output terminal. The control circuit includes a monitoring transistor within the same chip as the output transistor circuit, a selected one of the output resistance and input signal of the output transistor circuit being controlled in accordance with the magnitude of the drain current of the monitoring transistor to adjust the amplitude of the signal applied to the transmission line. Transmission with transmitting and receiving ends having a well-defined transmission waveform is obtained, thereby making possible high-speed signal transmission between LSI chips.

    摘要: A semiconductor integrated circuit system having a function of automatically adjusting an output resistance value with reference to a temperature of an LSI which is operating. When a count value obtained from a counter by counting the output of a timer becomes equal to a predetermined value, a temperature sensor measures temperatures of LSIs. If a temperature fluctuation measured from a previous measured value is greater than a predetermined width, then a control apparatus issues an output resistance value adjustment request signal to output resistance adjustment units of the LSIs. When receiving the output resistance value adjustment request signal, the output resistance value adjustment units stop the signal transmission between the LSIs, adjust output resistance values of output circuits in such a manner that the output resistance values are matched with a characteristic impedance of a transmission line, and maintains the adjusted output resistance values until the output resistance value adjustment units receive next output resistance value adjustment request signal.
