MC_XC 2X_JITTER
Figure 20 Approximated Accumulated PLL Jitter
Note: The specified PLL jitter values are valid if the capacitive load per pin does not
exceed C_L = 20 pF.
The maximum peak-to-peak noise on the pad supply voltage (measured between
V_DDPB pin 100 and V_SS pin 1) is limited to a peak-to-peak voltage of V_PP = 50 mV.
This can be achieved by appropriate blocking of the supply voltage as close as
possible to the supply pins and using PCB supply and ground planes.
