Abstract

A clock generator for generating a clock equivalent to a target clock which is an input clock divided by a non-integer ratio is disclosed. The clock generator comprises a clock divider configured to receive the input clock and divide the input clock with a reconfigurable dividing ratio; and a control circuit controlling operations of the clock divider to divide the input clock by a first dividing ratio to generate a first number of cycles of a first clock in a frame, and divide the input clock by a second dividing ratio to generate a second number of cycles of a second clock in the frame, wherein a difference between a period of the frame and a cumulative time of the first number of cycles of the first clock and the second number of cycles of the second clock is less than a threshold value.
