CLOCK CHARACTERISTICS (Cont’d)
12.5.5 PLL Characteristics
Note:
1. Data characterized but not tested.
The user must take the PLL jitter into account in the application (for example in serial communication or
sampling of high frequency signals). The PLL jitter is a periodic effect, which is integrated over several
CPU cycles. Therefore the longer the period of the application signal, the less it will be impacted by the
PLL jitter.
Figure 94
cies of less than 125KHz, the jitter is negligible.
