Data driving device, and display apparatus including the same

Abstract

A data driving device according to an embodiment of the present disclosure includes: a plurality of data driving circuits, wherein each of the plurality of data driving circuits includes: a clock recovery unit configured to recover display data and an internal system clock from image data received from a timing controller, and generate a plurality of candidate reference clocks having a predetermined phase difference using the internal system clock; and a data processing unit configured to calculate a timing difference between a clock training symbol of the display data and the internal system clock, and generate an output clock synchronized with another data driving circuit based on the calculated timing difference between the clock training symbol and the internal system clock.
