<p>PROBLEM TO BE SOLVED: To provide a clock generator which can reduce its space and also can decrease the noises without remodeling its substrate by providing a capacitor part to prevent the noises that are generated at a clock generation part. SOLUTION: This clock generator 1 consists of a clock generation part 2 which generates an output clock signal 6 and a capacity control capacitor part 3 which secures a bypass between a power supply signal 4 that supplies the power to the part 2 and a GND 5. A capacity setting signal 7 is inputted to the part 3 from the outside to set the capacity of a capacitor. That is, the part 3 is previously built into an inside idle space of the generator 1 to prevent the electrically unstable states of the signal 4 and the GND 5 and also to prevent the noises that are generated at the part 2. Therefore, no space is necessary on a circuit substrate for the capacitor and a wiring pattern.</p> |
