  • Data transmitting and receiving device
    Patent number: 11936409
    Abstract: A transmitter and a receiver are provided. The transmitter includes a processing unit configured to receive a clock signal and a data signal, set a value of a consecutive identical digit (CID) value related to the data signal and generate a modulation signal during a unit interval (UI) based on the data signal and the CID value, and a transmitter driver configured to output output signals having different voltage levels during the unit interval by receiving the modulation signal.
    Type: Grant

  • Differential signal processing device using advanced braid clock signaling
    Patent number: 11095484
    Abstract: A differential signal processing device is described which includes an encoder configured to encode input data into one or more differential signals and a transmitter configured to sequentially transmit the one or more differential signals using a plurality of transmission lines. The encoder converts a plurality of bits, corresponding to a transmission time interval, among the input data into an encoding code array in the transmission time interval obtained by increasing an encoding unit time, encoded for each of the one or more differential signals, by an integer multiple.
