    摘要: A first semiconductor integrated circuit is connected to a second semiconductor integrated circuit with a cable. In the first semiconductor integrated circuit, when a power supply voltage becomes less than a set voltage detection level, a voltage-detecting circuit outputs a voltage-detected signal to lower the voltage of the cable and to stop the operation. The second semiconductor integrated circuit detects the decrease in the voltage of the cable to recognize the halt of the operation of the first semiconductor integrated circuit. In the first semiconductor integrated circuit thus configured, in testing the operation under low-voltage conditions in which the power supply voltage is less than the set voltage detection level, the voltage-detecting circuit receives a control signal from an external terminal to stop the operation forcibly. Consequently, even when the power supply voltage is made lower than the set voltage-detecting level, the first semiconductor integrated circuit properly operates until the power supply voltage reaches a predetermined lower limit of operating voltage. Thus, evaluation of operation is possible under low-voltage conditions.

    摘要: A synchronization circuit includes a state detection circuit for outputting a control signal according to the temporal relationship between a transition point of an input signal and an edge of a synchronization clock, a delay selection circuit for adding a delay to the input signal based on the control signal, and a latch circuit for synchronizing the signal outputted from the delay selection circuit with the synchronization clock. Therefore, synchronization of the input signal can be carried out without adding latency to the input signal.

A second clock generation circuit (11) has a variable transmission characteristic, and produces a fourth clock signal obtained by multiplying the third clock signal by N. A parallel/serial conversion section (12) converts the parallel data signal, which has been converted by a scaler (16), to the serial data signal in synchronism with the fourth clock signal. A frequency divider (13) produces a fifth clock signal obtained by dividing a frequency of the fourth clock signal by N.

    摘要: In a signal receiving circuit there are provided N input detection circuits 2a to 2n for receiving clock signals S1-c to SN-c included in N channels of signals S1 to SN. Each of the input detection circuits 2a to 2n detects the transition of the input signal of the corresponding channel and further confirms that the signal of the corresponding channel is being received after the transition detection to thereby detect the input of the signal of the corresponding channel. The selection circuit 3 selects and outputs the clock signal and the data signal in the signal of the channel of which the input is detected. The selected output signal is successively subjected to input processes through one each of the phase synchronization circuit 4, the serial/parallel conversion circuit 5, etc., which are shared by N channels.
