Calculation of register value for audio PLL

[skajam66]

Hi,

I'm looking at the nrf5340 PS v1.2, page 75 & 76 regarding the audio clock PLL. Using the formulae given, I'm finding that the register value that yields the closest to 12.288MHz is 39846 (12.288005MHz). This differs from the table on P76 that gives a value of 39854. Is the PS in error or am I?

No problem at all, AC - I am happy to help!

I also thought I should mention that I discovered a typo in the MAX register value for the 11 MHz range of table 3, the value should be 18068 instead of 16068 as it says currently. We have created an internal ticket to have this fixed.
Thank you for bringing this to our attention!

Please do not hesitate to open another ticket if you should encounter any issues or questions in the future.

Good luck with your development!

Best regards,
Karl
