Shaded section on the VCO and Crystal waveforms indicates that the VCO and crystal oscillator are active, and there is a valid clock.
Note: Each supply pin must have an individual decoupling capacitor on test circuit at 0.1 µF.
Note: All capacitors must be placed as close to the pins as is physically possible.
