Hi community.

Our customer have video ADC clock frequency question.

Would you please Answer tomorrow 23 Oct, by 2015.

 

How many MHz speed of proc_clk input frequency of video AFE blocks .?

Refer from 9.10.13 Video ADC clock.

 

At frequencies below the formula is correct?

From 9.6.1.1 Typical PLL Configuration

PLL6(video PLL)     PLL output=24M*44.33=1064MHz(This is  PLL6main clock)

                                 CCM_CSCDR1=1064/4=532MHz

                                 Video ADC clock=532/4=133MHz

                                 video ADC clock divide by 2 clock=66.5MHz

 

From Chapter 61  61.1 Introduction  of Figure 61-1. Video subsystem block diagram

data clk= 66.5MHz
