The time has come to investigate the production part of things.

You typically select a crystal with sufficient tolerance (total better than 40 ppm) and use the appropriate load capacitors.&nbsp;</p> <p>The nRF53 series have built-in and selectable capasitors to do without external load caps.&nbsp;</p><div style="clear:both;"></div>
