Hello
Challange to find a 25MHz HSE crystal due to extended lead times.
Please let me know if this quartz crystal will work?
20PPM
From my point of view I think it will work.
Please have a look and confirm. Thank you for your help!

The STM32 can use a broad range of crystals and frequencies, you'd need to run the math and determine the suitable capacitors, and perhaps resistors. Perhaps work with your FAE to establish a number of suitable crystals.
What's the application? That's going to drive the performance requirements of the crystal.
Radio, Ethernet, CAN and USB have expectations.

Hello Tesla
Thanks, yes I have USB but no Ethernet or CAN.
I have done the math and my conclusion is that the CL needs to be below or equal to 10pF, should be 6-8 for a better margin since the trance will add xpF. Problem is still the stock.
