https://devzone.nordicsemi.com/f/nordic-q-a/59602/nrf53-pdm-clocksHi team Nordic, Looking in the nrf53 datasheet, it seems like the PDM clocks are the same (peripheral) as the nrf52, is this correct? You usually wanna run the newer high-end MEMS @ 3.072MHz. Can you please shed some light if this is possibleen-USTelligent Community 13Mon, 30 Mar 2020 18:53:39 GMThttps://devzone.nordicsemi.com/thread/242544?ContentTypeID=1Mon, 30 Mar 2020 18:53:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5ac0b71b-0336-4910-9c5f-a0642abbabda&#216;yvind<p>Hello again David,&nbsp;&nbsp;</p> [quote user=""]You usually wanna run the newer high-end MEMS @&nbsp;3.072MHz.[/quote] <p>&nbsp;<br />Yes, according to our R&amp;D team you should be able to achieve this frequency. By using the ACLK input:<br /><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-66eaea6cd56b49359c2d42d9c8700a10/pastedimage1585594161145v2.jpeg" alt=" " /></p> <p>You should be able to calculate the frequency using the PDMCLKCTRL equation found in <a href="https://infocenter.nordicsemi.com/topic/ps_nrf5340/pdm.html#concept_yyl_vv2_yr">Master Clock Generator</a>.<br /><br />Let me know if anything is unclear!<br /><br />Kind regards,<br />Øyvind</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/242373?ContentTypeID=1Mon, 30 Mar 2020 11:08:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c0a43ef5-b45c-48b6-be1a-2c6078e5b99f&#216;yvind<p>Hello David,&nbsp;</p> [quote user=""]Looking in the nrf53 datasheet, it seems like the PDM clocks are the same (peripheral) as the nrf52, is this correct?[/quote] <p>&nbsp;Yes, this is correct.</p> [quote user=""]Can you please shed some light if this is possible on the new nrf53 series?[/quote] <p>&nbsp;I need to forward it to our R&amp;D team.
