ADCCLK/SYNCHRONIZATION EVENTS
1 _{Necessary / No Sampling Events Occur}
2 _{Beginning of Synchronization / Samples Green (N-1) / Converts Unkown Dummy Value}
3 _{Samples Blue (N-1) / Converts Green (N-1)}
4 Samples Red (N) / Converts Blue (N-1)
5 _{Synchronization / Samples Green (N) / Converts Red (N)}
6 _{Samples Blue (N) / Converts Green (N)}
7 _{Samples Red (N+1) / Converts Blue (N)}

9 Dummy Pixel (N-1) Valid Generated From ADCCLK #2
10 _{GRN Pixel (N-1) Valid Generated From ADCCLK #3}
11 _{BLU Pixel (N-1) Valid Generated From ADCCLK #4}
12 RED Pixel (N) Valid Generated From ADCCLK #5
13 GRN Pixel (N) Valid Generated From ADCCLK #6
14 _{BLU Pixel (N) Valid Generated From ADCCLK #7}
Note: Green Channel is Synchronized on the First Rising Edge of ADCCLK After the Falling Edge of VSAMP
