Hi,

Thanks for contacting us.
For high frequency clock only external crystal (or external resonator) can be used , there is no option to use active external clock signal as clock source for high frequency clock.

Best regards,
Ressa

Hi, thanks for highlighting this, it could be an option, however it is not favorable due to the package being a lot smaller than any other component making the production more complex and expensive.

Did you look at the SiT11100? Seen a solution using this with the nRF54L15 that seems to work.
