Abstract: A control circuit for command signals of a clock generator includes a power supply end, an output end, a control end, a diode, a first resistor and a second resistor. The first resistor, the diode, and the second resistor are connected in series between the power supply end and the ground. The diode has an anode connected to the first resistor and a cathode connected to the second resistor. The control end is connected to a node between the diode and the second resistor; the output end is connected to a node between the diode and the first resistor. The output end outputs the command signals to the clock generator.
