Abstract: An electronic circuit includes a clock recovery circuit that generates a first reference clock signal based on first reception data and generates a second reference clock signal based on second reception data received after the first reception, a sampling clock generator that generates a sampling clock signal having a phase based on a phase difference between the first reference clock signal and the second reference clock signal, and a sampler that recovers the second reception data based on the generated sampling clock signal.

Abstract: An electronic device includes; a timing controller that generates a command to-be-sent to a display driver integrated circuit (DDI) selected from among a plurality of display driver integrated circuits (DDIs) connected to the timing controller through data lines and a shared channel The DDI is selected by a DDI control signal transferred from the timing controller to the DDI through a corresponding data line among the data lines, and the command is transferred from the timing controller to the DDI through the shared channel

Abstract: A display driver circuit includes a receiver that receives a still image or a moving image, a frame buffer that stores the still image received by the receiver in a still image mode, an image processor that performs an image enhancement operation on the moving image transferred from the receiver or the still image transferred from the frame buffer, and a motion processor that performs a motion compensation operation using a current frame output from the image processor and a previous frame stored in the frame buffer in a moving image mode. The previous frame is data which, in the moving image mode, are processed by the image processor before the current frame and are then stored in the frame buffer. The previous frame is output from the frame buffer to the motion processor in synchronization with the current frame.
