摘要:
A pixel clock generator is provided. The pixel clock generator includes a phase-locked-loop (PLL) circuit that generates, from an oscillation signal having a first frequency of tens of MHz, a multi-phase oscillation signal having a second frequency of several GHz; and a frequency/phase adjusting circuit that synchronizes the multi-phase oscillation signal with a horizontal sync signal to generate a first oscillation signal, frequency-divides the first oscillation signal to generate a second oscillation signal, and adjusts a phase of the second oscillation signal to generate the pixel clock.
