In my project it can happen, that the LSE gets blocked due to a CSS failure detection after repowering. I found this good article on the ST community which maches alomost with my case: https://community.st.com/t5/stm32-mcus-products/lse-fault-recover...

I'm in doubt about the transconductance parameter of the HSE oscillator in STM32L443.To select an appropriate cristal I studied AN2867.If the datasheet of STM32L443 which notes "Gm = 1.5mA/V" refers to gm the transconductance of the passive elements ...

Thank you for explaining the complicated topic and braking it down to the necessery timing parameters. Very helpful!

I received this answer from the application team by e-mail:First:Gm=1.5mA/V means the max. allowed transconductance of the crystal which corresponds to Gm_crit_max in the AN2867 document.Second:“The Cs use a little assumption which more depends on la...
