Abstract
A clock generator is provided which comprises a reference signal generator; a voltage controller/generator to generate a dot clock signal; a frequency divider to divide the frequency of the dot clock signal supplied from the voltage controller/generator; a phase comparator to detect a phase difference between the reference signal supplied from the reference signal generator and a signal supplied from the frequency divider; a frequency division ratio setter to set the frequency division ratio in the frequency divider to less than a quotient resulted from division of a total number of horizontal pixels in each of the video signals by a greatest common divisor of the total of horizontal pixels in the video signal having one format and total number of horizontal pixels in the video signal having the other format; and a frequency division ratio selector to select a frequency division ratio set by the frequency division ratio setter correspondingly to a format of a video signal.
