https://devzone.nordicsemi.com/f/nordic-q-a/120292/nrf9160-ticks-accuracyDear Sir / Madam, We are testing with NRF9160 and building on top of k _uptime _ticks, I find the precision of the ticks clock to be ~70 ppm, while testing on my desk. According to the specification. https://docs.nordicsemi.com/bundle/ps_nrf9160/pageen-USTelligent Community 13Mon, 31 Mar 2025 11:58:23 GMThttps://devzone.nordicsemi.com/thread/529781?ContentTypeID=1Mon, 31 Mar 2025 11:58:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e189ecd5-bd22-4438-b1a0-85bf534895c8Hung Bui<p>Hi Sjors,&nbsp;<br />The 32kHz RC internal oscillator has much lower accuracy than 70ppm (according to spec it&#39;s 30%). So I think the chip is using the XTAL already.<br />Could you give the part number of the crystal and the layout and schematic of the board ?<br />Could you tell how you measured the accuracy of the ticks?&nbsp;</p><div style="clear:both;"></div>
