Drive the NRF52840 with an external 16MHz Clock instead of the 32MHzhttps://devzone.nordicsemi.com/f/nordic-q-a/38127/drive-the-nrf52840-with-an-external-16mhz-clock-instead-of-the-32mhzHey Guys, I am working on a Project with a NRF52840 and it works pretty fine with an 32MHZ external crystal to generate the internal 64MHZ sysclock. But now, I want to replace the 32MHz crystal with an 16MHz crystal to share this clock with anotheren-USTelligent Community 13Mon, 03 Sep 2018 14:20:29 GMTRE: Drive the NRF52840 with an external 16MHz Clock instead of the 32MHzhttps://devzone.nordicsemi.com/thread/147009?ContentTypeID=1Mon, 03 Sep 2018 14:20:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f59f181-03fd-4357-bebe-018a0d7dea6adeveloper1.0<p>Hey,</p> <p>what a pity.

See the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52840.ps/clock.html?cp=2_0_0_4_3_3_1#unique_1777303707">PS</a> for the crystal requirements.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
