That it's a clock which could be used for SAI1 is explained above at PLLP; still, the signal's name is PLLSAI2CLK, however confusing that is.

Hi
Waclawek.Jan
,Thank you for bring this to our attention.
In fact, PLLSAI1CLK comes from PLL block and PLLSAI2CLK comes from PLLSAI1 block as described in datasheets.
This is done to differentiate the PLL sources.
So, to avoid confusion, we proposed tochange PLLSAI1CLK andPLLSAI2CLK in the reference manuals and datasheets bynew significant names.
Best Regards,
