https://devzone.nordicsemi.com/f/nordic-q-a/33390/fa-238-xtalI have read the nAN24-13 application note as well as the crystal selection portion of the nRF24LE1 and nRF24LU1 data sheets and I am still undecided about this crystal https://www.mouser.com/ProductDetail/Epson-Timing/FA-238-160000MB-K3?qs=sGAEpiMZZMsBj6bBr9Q9aXmxIa9b7yjIven-USTelligent Community 13Mon, 16 Apr 2018 06:37:18 GMThttps://devzone.nordicsemi.com/thread/128382?ContentTypeID=1Mon, 16 Apr 2018 06:37:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:01faaef6-2039-412f-b654-91a938a1d22aAndreas<p>Hi,</p> <p>&nbsp;</p> <p>Your crystal has slightly higher C_L, and the same can size as the note specifies start-up time for, so it should be a little higher, but within specificaitons. Still, you should measure the start-up time (instructions in <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.appnotes/dita/appnotes/pdflinks/nan_24-13.html?cp=10_14">this appnote</a>) in your design and use a crystal with a lower C_L if needed, this will lower your current consumption as well.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
