Note: The specified PLL jitter values are valid if the capacitive load per pin does not exceed C_L = 20 pF with the
maximum driver and sharp edge.
Note: The maximum peak-to-peak noise on the power supply voltage, is limited to a peak-to-peak voltage of
V_PP = 100 mV for noise frequencies below 300 KHz and V_PP = 40 mV for noise frequencies above 300 KHz.
These conditions can be achieved by appropriate blocking of the supply voltage as near as possible to the
supply pins and using PCB supply and ground planes.
