STM32F446 MCO2 from I2SPLL

Question asked by waclawek.jan on Sep 13, 2017

 

 

There's no source of PLLI2S signal mentioned anywhere else on the schematics, nor elsewhere in RM0360 (although the string occurs quite often as it's the name of the PLLI2S sub-module).

 

My personal guess is, that this MCO2 input is fed from PLLI2SR, i.e. the R output of PLLI2S submodule; but I'd love to hear some qualified comment from ST.

 

Thanks,
