I'm trying to define how the FB pin should be connected when only using a single NTSC (CBVS) on AIN1 as I don't require the switching that FB provides. I'll be using ADC0 and the SDP to output 10 bit 4:4:2. Is it just a case of setting the FB_PWRDN bit when initializing the decoder? On the 7181C data sheet Pg19 section 3.4 there are listed 4 basic modes yet none suit my configuration and two don't even use the FB pin. Also if there are any recommended scripts for the above configuration it would be greatly appreciated.
