I have a question regarding internal PLLs.
I would like to know the jitter of the PLL in the STM32H743XGH6.
I could not find a PLL Characteristics table that would have the answer I want to know.
I have seen posts about jitter in various other PLLs.
However, I cannot decide how much to trust that information because of the different models.
Perhaps it is very unlikely that these jitter values will adversely affect the system, but I would like to have some data to base my decision on.
Does anyone know of any data on this?

Hello,
The PLL jitter is provided in the datasheet of the product:
Rev Y:
Table 49. PLL characteristics (wide VCO frequency range)
Table 50. PLL characteristics (medium VCO frequency range)
Rev V:
Table 146. PLL characteristics (wide VCO frequency range)
Table 147. PLL characteristics (medium VCO frequency range)
