&lt;p&gt;I have escalated this internally.&lt;/p&gt;

&lt;p&gt;That would be good news, did you get confirmation from the internal team?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nRF52833 external 32MHz TCXO</title><link>https://devzone.nordicsemi.com/thread/568909?ContentTypeID=1</link><pubDate>Wed, 08 Jul 2026 13:31:29 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:79e42107-b065-4a7d-9b63-a487545b1625</guid><dc:creator>Priyanka</dc:creator><description>&lt;p&gt;Hi Ryan,&lt;/p&gt;
[quote user=""] is it possible to use an external TCXO as the source for the 32MHz?[/quote]
&lt;p&gt;This should be possible. The nRF52833 &lt;a href="https://docs.nordicsemi.com/r/bundle/ps_nrf52833/page/clock.html"&gt;does support using an external clock source &lt;/a&gt;in place of the crystal oscillator for the HFCLK (64 MHz, driven by an external 32 MHz source).&amp;nbsp;A TCXO is a better-quality clock that changes much less with temperature.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Though I am not sure if&amp;nbsp;the nRF52833&amp;#39;s HFXO input accepts a TCXO clipped-sine output directly. Will verify this internally and get back to you.&lt;/p&gt;
