stm32g030 External crystal pin map

Hi everyone
I use STM32G030. I'm gonna set the clock system to HSE on the External crystal, but I couldn't find the proper RCC_OCS_OUT.
What are the MCU's crystal correct pins?
Please help me set the correct pinout.
Thank you

Hello @MTora.1 ,

You need a crystal oscillator (XO) not a crystal (XTAL) as OSC_OUT is not available in this MCU part number.

Please refer to this article: 

Do you know when to use a crystal or an oscillator?

This chip does not have an OSC_OUT pin and cannot use a crystal. Only bypass mode is available.

The LQFP48 package has this pin. Others do not.

I use LQFP32.

I see that. That is why I said this chip does not have the OSC_OUT pin available.

That's  normal. Did you refer to the datasheet?:

No OSC_OUT available in LQFP32.
