1.2 Precautions for PLL Frequency Synthesizer
Make the supply voltage stable to use the PLL frequency synthesizer.
For ripple with the supply voltage 5V, keep below 10kHz as frequency, below 0.5V (peak to peak) as
voltage fluctuation band and below 1V/mS as voltage fluctuation rate.
For ripple with the supply voltage 3V, keep below 10kHz as frequency, below 0.3V (peak to peak) as
voltage fluctuation band and below 0.6V/mS as voltage fluctuation rate.
