Since this IC requires an external clock source, and Here is said that this is possible (or at least I think). 1.can it be done just using the nRF and connectingen-USTelligent Community 13Wed, 29 Dec 2021 15:20:25 GMThttps://devzone.nordicsemi.com/thread/345386?ContentTypeID=1Wed, 29 Dec 2021 15:20:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5f867ee1-1bf3-4a82-97a0-44672765741bOswaldoP<p>I confirm it can be done just following the documentation, thank you.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/342876?ContentTypeID=1Fri, 10 Dec 2021 10:17:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e7fbb8b6-8738-4c5f-a57c-b8d8c9753bcdJared<p>Hi,</p> <p>Seen from the nRF52 side, this is OK.&nbsp;</p> [quote user=""]<p>1.can it be done just using the nRF and connecting one end to the External clock input of the IC?</p> <p></p>[/quote] <p>Yes, as shown in the white paper you linked.&nbsp;</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
