https://devzone.nordicsemi.com/f/nordic-q-a/31248/nrf52810-oscilator-pinHello All, I am using 32 pin nRF52810 chipset. Crystal have two pin and it will work as in sch. (Xin and Xo) when using Osc (which is an external clock generator) there is only one pin, so which pin is the input clock for the Nordic Chip? whenen-USTelligent Community 13Thu, 08 Mar 2018 09:11:58 GMThttps://devzone.nordicsemi.com/thread/123374?ContentTypeID=1Thu, 08 Mar 2018 09:11:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ab9e3cd2-9407-45b7-9199-cadfa37520b4haakonsh<p>Hey pktron,</p> <p>From&nbsp;<a title="32.768 kHz crystal oscillator (LFXO)" href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52810.ps/clock.html?cp=2_2_0_4_3_1_3#concept_pln_z5y_2q">32.768 kHz crystal oscillator (LFXO)</a>:&nbsp;</p> <p>&quot;Rail-to-rail clock signal applied to the<span>&nbsp;</span><dfn>XL1</dfn><span>&nbsp;</span>pin.
