  • Patent number: 11134189
    Abstract: An image device may include a clock generator to generate a first output clock of a first frequency, a link layer to generate a control signal for changing the first frequency and output first parallel data including first frame information, a detector to generate a collision avoidance command to change the first frequency to a second frequency during a vertical blanking time, and a frequency changer to receive the collision avoidance command from the detector and transmit a frequency change command to the link layer. The link layer transmits the control signal to the clock generator based on the frequency change command. The vertical blanking time is a time period from a first time point at which the first parallel data is not output from the link layer to a second time point at which second parallel data is output.

  • Patent number: 10992447
    Abstract: A high-speed interface apparatus and method of correcting skew in the apparatus are provided. A high-speed transmitter includes a transmission D-PHY module that generates and transmits a clock signal through a clock channel, generates a deskew synchronous code and test data in response to a deskew request signal, transmits the deskew synchronous code followed by the test data through a data channel, and transmits a normal synchronous code followed by normal data through the data channel in normal mode.
