What is the duty cycle tolerance for the i.MX6D XTALI input port?

[torus1000]

Hi,

We plan to provide clock from external Oscillator to the XTALI pin.

We were looking for the XTALI spec but we couldn't find yet.

About Oscillator specification in i.MX6DQ.

Input spec for XTALI pin when using external clock source

Is there any specification of duty cycle for XTALI input?

Can anyone help me?

Hello torus,

     For i.MX6 serials processors, their XTALs has the same architecture, see below, please!

So if you want to use Oscillator 24MHz, not Crystal 24MHz, XTALO should be input PAD, not XTALI. See schematic of i.MX6UL, we can get usage from it. see below, please!

you can download full schematic from NXP website.

The oscillator's output precision, 30ppm is OK.

Have a nice day!
