https://devzone.nordicsemi.com/f/nordic-q-a/73020/nrf52832-pcbHi I have two questions about nRF52832 QFAA Custom PCB. 1) When I calculate load capacitance for external crystal. Is this fomula(C1,C2 =2Cl - Cstray {Cstray = 4pF}) correct?? 2) I know C6(=DEC2) in nrf52832 QFAA reference circuiry. en-USTelligent Community 13Fri, 19 Mar 2021 13:03:27 GMThttps://devzone.nordicsemi.com/thread/300934?ContentTypeID=1Fri, 19 Mar 2021 13:03:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:54fa9ce4-bf31-40c4-b6e9-89fc989c64fbketiljo<p>1. Yes. For a crystal with CL = 8 pF, use 12 pF load caps.&nbsp;</p> <p>2. Yes, no problem.&nbsp;</p> <p></p> <p>Note how C3 here is grounded only to the VSS_PA pin (31):&nbsp;</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/nRF52832-matching-network.png" alt=" " /></p><div style="clear:both;"></div>
