It's not about dividing frequencies. I have a clock (HF) in my microcontroller that is obtained from a pll that multiplies a reference crystal clock frequency. I would like to use the so called "spectrum spreading" in order to modulate the clock (HF) with the low frequency, reference clock (from the crystal). The result should be that when I look at the spectrum of the HF clock (output of the pll), there would not be narrow spike at the HF, but a larger band with a smaller dB value. I tried a low cost solution, by just inserting a capacitor but it creates only 2 additional smaller spikes in the spectrum around the HF one, while the HF is unchaged. And it creates instability in locking the pll. So I need another solution, low cost, if it exists. ??? Dze
