[imx6q] frequency deviation

jackeyko — Mon, 06 Feb 2017 01:47:59 GMT

Hi NXP,

We changed 24MHz to 24.576MHz for audio clock.

But the frequency was actually 24.5745 MHz in CLKO1 . Please find the attahced file.

I would like to know why is 24.5745 MHz measured.

Thanks,

Jackey

Hi Jackey

24.5745 MHz may be measured due to crystal accuracy and

temperature drift. In general frequency can be adjusted by tuning

loading capacitors.

Hi Igor,

Thanks for your message.

I will check the crystal accuracy and temperaure drift and adjust the loading capacitors.

Thanks,

Jackey
