The internal crystal oscillator uses the external quartz crystal as the basis of its frequency reference. The frequency of the internal crystal oscillator or external reference clock signal is multiplied by the PLL. The VCO within the PLL operates over a range of 800 to 1800 MHz. Its output is scaled by a divider that is configured by either the serial or pa.
