Clock signal generating device |
摘要 |
A clock signal generating device is described, having an oscillator and a PLL connected downstream thereof. The clock signal generating device is distinguished by the fact that a phase shifting device is provided between the oscillator and the PLL. This phase shifting device can temporally shift the edges of the signal output by the oscillator to a variable extent, and feeds the resultant signal to the PLL as an input signal. Such a clock signal generating device makes it possible to realize a spread spectrum oscillator which is constructed in a simple manner and can be made small.
