I want to use a different PLL block than PLL1 to leave PLL1 specific to SYSCLK generation; and for example use PLL2 to generate my arbitrary clock.I see that SAI blocks use for example PLL2 or PLL3 but I don't know if it is possible to make an arbitr...

my goal is to use this board in [-40°C +85°C] climatic chamber.Regards:)Oliver

Correct for the calculus according 10MHz(2^7 * 5^7), so I'll try to find an other low power VCXO.I need a VCXO to avoid a big jitter on the sampling clock input of ADC, and so keeping a good SNR on ADC.My ADC is an external ADC, not an internal STM32...

Hi, reading the reference manual m0456 v2 (chapter 11.8.6 RCC clock configuration register 1 RCC_CFGR1)), I understand that only PLL1_r_ck can be used to drive the MCO output, no possibilities to use other PLLs.Is my understanding correct?

STM32U585I think using VCXO at 10MHz and use STM internal PLL to increase the frequency to 16,777216 MHz (2^24Hz).In my system my need is to have a VCXO to lock an ADC sampling clock to an external time reference, the 10MHz is one of common frequenci...

Thank you TDK, I'm going to check the BOM to retrieve the operationnal temperature of the evaluation board Nucleo 144

According your answer, to check the component's temperature, where can I find the Bill Of Materials for the nucleo-u575zi-q evaluation board ?

is it possible to use another output than MCO to generate an arbitrary clock (16.777216MHz) from an internal PLL block?

What is the temperature range of the nucleo-u575zi-q evaluation board ?
