1. PLL0IN clock retrieved directly from either internal RCOSC or external FXOSC clock. Input characteristics are granted

when using internal RCOSC or external oscillator is used in functional mode.

2. If the PLL0_PHI1 is used as an input for PLL1, then the PLL0_PHI1 frequency shall obey the maximum input frequency

limit set for PLL1 (87.5 MHz, according to Table 21).

3. Jitter values reported in this table refer to the internal jitter, and do not include the contribution of the divider and the path to

the output CLKOUT pin.

4. VDD_LV noise due to application in the range VDD_LV = 1.20 V±5%, with frequency below PLL bandwidth (40 kHz) will be

filtered.
