  • Patent number: 11394376
    Abstract: An XTC circuit includes delay circuits, differentiated signal generating circuits, and an amplitude adjusting and adding circuit. A signal Da, which is one aggressor signal, is input to the differentiated signal generating circuit after being delayed by the delay circuit, and the differentiated signal generating circuit generates a differentiated signal having a differentiated waveform of the signal Da. In the amplitude adjusting and adding circuit, the differentiated signal generated by the differentiated signal generating circuit is amplitude-adjusted to become a current signal, and the differentiated signal after the amplitude adjustment is current-added to the signal Db.

  • Patent number: 11329669
    Abstract: A multi-lane serializer device 1 includes serializer circuits 101 to 10N and a controller 20. A phase difference detector of each serializer circuit detects a phase difference between a load signal and a first clock, and outputs an abnormal detection signal to the controller 20 when the detected phase difference is abnormal. When the controller 20 receives the abnormal detection signal from any of the serializer circuits, the controller 20 transmits a batch reset instruction signal to all the serializer circuits. Then, in all the serializer circuits, when a reset signal generator receives the batch reset instruction signal output from the controller 20, the reset signal generator transmits a reset instruction signal to a load signal generator to reset the operation of a load signal generation in the load signal generator.

  • Patent number: 11323182
    Abstract: A transmitting and receiving device includes a controller, a driver, a specific pattern generator, a transmitting signal detector, an amplifier, a differential amplifier, an average current detector, and a received signal detector. In a non-signal period, the controller causes a current signal to be input from the driver to a laser diode and causes an optical signal to be output from the laser diode. When an optical signal of a specific pattern output from the other-side laser diode reaches a photodiode over a period of length that depends on an average value of a current signal output from the other-side photodiode that receives the optical signal, the controller adjusts a magnitude of the current signal input from the driver to the laser diode based on the length of the period of the optical signal of the specific pattern.

    Abstract: A PLL circuit of one embodiment has a structure for preferably setting the FV characteristic of an LC-VCO. The PLL circuit includes a voltage controlled oscillator, a phase comparator, a charge pump, a loop filter, and an FV characteristic adjustment unit setting the FV characteristic. The voltage controlled oscillator has an FV characteristic indicating the relationship between a control signal and a frequency and outputs an oscillation signal having a frequency corresponding to the control signal based on the FV characteristic. The phase comparator detects a phase difference between an input signal and the control signal. The charge pump outputs a corrected voltage value changed according to the phase difference. The loop filter outputs a control voltage value changed in response to corrected voltage value variations. The FV characteristic adjustment unit generates an FV characteristic control signal by a mean corrected voltage value.
