This is a deviation for an individual part, once the initial frequency has been measured. 2. Guaranteed by characterization results. Table 47. MSI oscillator characteristics (continued) Symbol Parameter Condition Typ Max Unit Table 48. PLL characteristics Symbol Parameter Value Unit Min Typ Max(1) 1. Guaranteed by characterization results. fPLL_IN PLL input clock(2) 2. Take care of using the appropriate multiplier factors so as to have PLL input clock values compatible with the range defined by fPLL_OUT. 2- 24 MHz PLL input clock duty cycle 45 - 55 % fPLL_OUT PLL output clock 2 - 32 MHz tLOCK PLL input = 16 MHz PLL VCO = 96 MHz - 115 160 µs Jitter Cycle-to-cycle jitter - ±600 ps IDDA(PLL) Current consumption on VDDA - 220 450 µA IDD(PLL) Current consumption on VDD - 120 150 |
