In one of our application, we need to receive STANAG3350B differential signals, Convert it into Single ended and digitize RGsB signals.

We have selected AD8145 to receive Differential RGsB, and ADV7181C Video Decoder for Digitize.

I have few queries regarding the connectivity of the RGsB signals into Video Decoder.

   > As per the Functional Block Diagram shown in Page 3 of datasheet, ADC0 output is connected to Sync Extract and ADC0, ADC1 and ADC2 are connected to Standard Definition Processor block. ADC1, ADC2 and ADC3 are connected to Component processor Block.

   > If I connect inputs as recommended by datasheet (Page16, Table 8), Gs -> Ain6, R-> Ain5, B -> Ain4 and use ADC0, ADC1 and ADC2 respectively, can I use Sync Extract to extract Sync on Green, and use CP block for processing RGB. How it will work ?

   > Please recommend how I can extract Sync from Green and process RGB video received in STANAG3350B standard.
