IMX 6 Solo Free run clock

[DK4509]

Hi,

I am planning to provide on the CLK1_P/N pins a 133MHz clock of the IMX 6 solo processor.

Can I get a core clock frequency output, near to 1GHz if 133MHz is provided to CLK1_P/N signals?

If so, how will the calculation be determined on?

Thanks,

Dinesh

Hi @DK4509,

I hope you are doing well.

Please refer to the reference manual IMX6SDLRM section 18.5.1.3 PLL reference clock.
i.e For ARM PLL, the formula for PLL output frequency is
PLL output frequency = Fref * DIV_SEL/2

Here DIV_SEL is CCM_ANALOG_PLL_ARM[DIV_SELECT] bit.
and Fref is a reference clock.

Thanks & Regards,
