IMX6S spread spectrum for PLL2 PFD[0:2]

Hi,

As my understanding PLL2 (system PLL) 528Mhz only supports the spread spectrum in i.MX6S.

Does the PLL2_PFDs (PFD0=352MHz, PFD1=594MHz, PFD2=396MHz) also should support the spread spectrum ?

 

PLL2_PFD is deriverd form PLL2 according to following formula.

PLL2_PFD =  PLL2 * (18/N)

(N is from 12 to 35)

 

According to additional PLL2_PFD, the function of the spread spectrum fades away ?

 

Regards,

Kanou
