https://devzone.nordicsemi.com/f/nordic-q-a/5414/nrf24l01-change-quartzHi all! May I use another quartz instead of 16 MHz? Will the output frequency equal to 2.4GHz/16, if I will be use the 1 MHz quartz? Or IC will not work? Is it possible to change the reference design for the RF frequency below 2.4GHz?en-USTelligent Community 13Wed, 04 Feb 2015 08:59:48 GMThttps://devzone.nordicsemi.com/thread/18899?ContentTypeID=1Wed, 04 Feb 2015 08:59:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2b334bb5-58df-47e2-9eba-bc682558e275Asbj&#248;rn<p>The 16 Mhx is used to directly create the 2.4 GHz carrier and the radio part of the chip will not work if you use a 1 MHz crystal instead. We are only testing our chips with 16 MHz crystal, but in theory it would be possible to have the radio working with a crystal outside 16 MHz with the carrier getting the same offset. However, this is outside of spec and we can&#39;t say anything on performance and would not recommend doing so, but for crystals fairly close to 16 MHz, it might work.</p><div style="clear:both;"></div>
