nrf53 PDM clocks

[dav01]

Hi 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 possible on the new nrf53 series?

Thx David

Hello David,

 Yes, this is correct.

Can you please shed some light if this is possible on the new nrf53 series?

 I need to forward it to our R&D team. Will get back to you as soon as I have an answer. 

Kind regards,
Øyvind

Hello again David,  

You usually wanna run the newer high-end MEMS @ 3.072MHz.

 
Yes, according to our R&D team you should be able to achieve this frequency. By using the ACLK input:

You should be able to calculate the frequency using the PDMCLKCTRL equation found in Master Clock Generator.

Let me know if anything is unclear!

Kind regards,
Øyvind
