I want to confirm about fractional-N synthesizer of i.MX6SDL CCM.
Please see my questions below.
Please see chapter 188.8.131.52.3 in IMX6SDLRM Rev.1.
I understand fractional-N synthesizer is used for RF application generally.
However, i.MX6 system PLL is not connected to RF module directly.
So I guess this fractional-N synthesizer is prepared for spectrum spread.
Is my understanding correct?
Please see chapter 184.108.40.206.4.
It says "It has a Fractional-N synthesizer" for Audio/Video PLL, also.
However, I cannot find a register for setting fractional-N synthesizer of Audio/Video PLL.
Is the discription misprint?
If there is a fractional-N synthesizer, could you let me know how to set it?
