USB UVC with STM32U5G9ZJT6Q is 60 MHZ PHY Clock possible

AA22

Hello everyone,

I am currently working on a project using the STM32U5G9ZJT6Q mcu with USB UVC. For my setup, I am providing: 

32 MHZ external clock to phy 

144 MHZ system clock 

In the documentation(TRM and CubeMX), the maximum external phy clock specified is 32 MHZ.

However I need to achieve a 60 MHZ PHY Clock, which seems to be supported by the hardware but isn't explicitly listed in CubeMX or the reference manual.

My questions are: 

Is it possible to configure the external PHY Clock to run at 60 MHZ? 

If so, does anyone have an example configuration or code snippet to achieve this?

Any insights or suggestions would be greatly appreciated!

Thank you in advance.
