Hi,
I designing a new design with STM32L471ZGJ6 MCU.
I connected crystal osc S.N. ECS-.327-12.5-1210B-N-TR to PC14, PC15 pins in MCU.
Is the value of the capacitors I connected correct? (see image below)
Is the connection correct?
Thanks,
Mor

Looks okay, keep in mind that you might have to play with the capacitor values, and probably bridge ( = 0 ohms) the resistors.
But you can't go wrong with having them on the board.

Hi,
Please refer to AN2867 Rev 15 "Oscillator design guide for STM8AF/AL/S, STM32 MCUs and MPUs " section 3.3 Load capacitance illustrated how to calculate the external capacitors.
