Use TCXO as LFXO (nRF52)

[mzi]

Hi, I would like to know, whether it is possible to use a TCXO with single output as a LFCLK source, i.e. connecting the TCXO output only to XL1, instead of connecting an xtal between XL1 and XL2.

Thanks,

Martin

Hi Martin,

On nRF52, the HFCLK was not made to work with external clock source other than the Xtal.

Thanks RK! I found the information in the online manual right now, I was working with PDF version of the manual until now where this information was missing completely. My bad.
