1. Resonator characteristics given by the ceramic resonator manufacturer.
2. LP mode is not recommended for 2 MHz resonator because the peak to peak amplitude is too small

To reduce disturbance to the RC oscillator, it is recommended to place decoupling
capacitors between V
PLL characteristics
Table 98.
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,
