PURPOSE: A synchronous compensating circuit is provided to prevent a degradation of a picture quality by selecting a clock signal suitable to an input data according to a selecting signal and providing the selected clock signal to a liquid crystal module. CONSTITUTION: A delay means(10) delays an input clock signal(CLK) during a wanted time. A selecting means(20) selects the clocks signal delayed through the delay means(10) according to a selecting signal inputted from the outside. The delay means(10) has a first buffer(11) for generating a first delayed clock signal(CLK1), a second buffer(12) for generating a second delayed clock signal(CLK2), and a third buffer(13) for generating a third delayed clock signal(CLK3). The selecting means(20) has a multiplexer(14) for selecting one signal among an input clock signal(CLKIN), a first delayed clock signal(CLK1), a second delayed clock signal(CLK2), and a third delayed clock signal(CLK3) according to selecting signals(SEL1,SEL2) inputted from the outside.
