摘要： An optical interconnect device includes a first substrate, a second substrate, an optical waveguide, an electrical wiring and a switching device. The first substrate has an electrical wiring circuit, an electrical-optical converter for converting an electrical signal to an optical signal, and a light emitting device for emitting a light. The second substrate has an electrical wiring circuit, an optical-electrical converter for converting the optical signal to the electrical signal, and a light receiving device for receiving the light from the light emitted device. The optical waveguide optically connects the light emitting and light receiving devices. The electrical wiring electrically connects the electrical wiring circuits of the first and second substrates. The switching device determines a fast signal of data to be transmitted via the optical substrate and a slow signal of data to be transmitted via the electrical wiring.

摘要： An optical interconnect includes a transmitter circuit, a receiver circuit and an optical signal transmission route. The transmitter circuit includes a control circuit and an electrical/optical converter circuit. The control circuit receives an input electrical signal and outputs a drive signal. The electrical/optical converter circuit includes a light emitting element and converts the drive signal to an optical signal. The receiver circuit includes an optical/electrical converter circuit and a data recovery circuit. The data recovery circuit includes a second trigger signal generator and a latch circuit. The optical/electrical converter circuit includes a light receiving element and a received-signal amplifying circuit. The light receiving element converts the optical signal from the light emitting element to an output current signal. The received-signal amplifying circuit converts the output current signal to a required digital voltage signal. The optical signal transmission route optically is connecting the transmitter circuit and the receiver circuit.

摘要： A sensor control circuit for controlling a sensor unit for measuring a physical value includes a timing controller which selects periodically one or more sensor units among multiple sensor units and converts an output signal from the sensor unit to a continuous serial input signal, an oscillator which receives the serial input signal input by the controller and outputs a frequency signal corresponding to the output signal detected by the sensor unit, a counter which counts for a predetermined duration a number of pulses of the frequency signal output from the oscillator, a data converter which converts the number of pulses to voltage data and outputs the data, and an RLC selector which inputs to the converter information indicating a characteristic value on which the number of pulses is based. The characteristic value is resistance, inductance or electrostatic capacitance. The sensor units measure physical values, respectively.
