A method for synthesizing a clock signal with multiple frequency outputs for use in a converter for converting a non-interlacing scan data into an interlacing scan data is disclosed. The converter provides a first reference clock signal with a frequency F 1. The method includes the steps of receiving the first reference clock signal with the frequency F 1 to generate and output a clock signal with a frequency F 1 xN, proceeding a divided-by-P 1 and a divided-by-P 2 operations on the clock signal with a frequency F 1 xN, respectively, to output a first output clock signal with a frequency F 1 xN/P 1 and a second output clock signal with a frequency F 1 xN/P 2, respectively. The value P 2 /P 1 correlates to a ratio of the pixel number of a horizontal scan line in the non-interlacing scan data to that in the interlacing scan data. In addition, a clock signal synthesizer with multiple frequency outputs is also disclosed.
