ABSTRACT:
A charge pump clock generating circuit and a method thereof are disclosed. The circuit includes a sync counter, a comparator, and a clock generating circuit. The sync counter receives a dot clock and a reset signal for accumulating a counting value according to the dot clock and resetting the counting value to a starting value when the reset signal is enabled. The comparator receives the counting value and outputs the reset signal when the counting value is greater than or equal to a preset value. The clock generating circuit receives a display clock and the reset signal and outputs a charge pump clock. The clock generating circuit transforms the logic state of the charge pump clock when the reset signal is enabled, and sets the charge pump clock to a first preset logic state when the display clock is transformed from a first state to a second state.
