Clockless transmission system and clockless transmission method

Abstract

A clockless transmission system includes display controller 101 and display driver 106. Display controller 101 includes data transmission circuit 102 configured to output general data obtained by multiplexing a clock by coding serialized pixel data for each pixel data during a data communication interval and also to output a predetermined control signal during a blanking interval. Display driver 106 includes clock and data recovery circuit 107 configured to output the pixel data from the general data transferred from the display controller and to increase a loop gain of a feedback loop in clock recovery such that the loop gain is larger than that when the general data is received, according to control data of the control signal, to recover and output a clock, and display driving circuit 109 configured to output a signal for driving a display based on the pixel data and the recovered clock.
