AD9984A to output 24-bit

Question

Hello 
 
 I want to ask if AD9984A can output 24-bit 444 RGB instead of 30-bits. 
 
 this is because I need to pair it with 2 (or 1) of ADV7343 which only accepts 24-bits... other DACs which can support 30-bits are expensive. 
 
 The design as a whole must get cvbs, s-video, ypbpr, rgb scart (sync on green, and csync), as well as rgbhv... then digitize that and output to all of them using a suitable dac. meaning if i input s-video, it gets converted, then dac will output to all other mentioned formats besides s-video itself. 
 
 I tried pairing adcs and dacs but could not do it on the cheap... 
 
 adv7181c seemed nice and supports all + still active but it does not output any 444 format which are compatible with the dacs. 
 
 for your help

Hi, 
 As per AD9984A/ADV7401/ADV7800 datasheet, Pin20 is dedicated for some other purpose So let us know in which IC that deals with CVBS signal on Pin20. 
 Kindly note you can generate Csync signal by using register ' HS_OUT_SEL' (Allows the switching of a CSync output on the HS pin). 
 i.e HS_OUT_SEL = 1, the CSync is output on the HS/CS pin. 
 Please refer below links which will help to generate the 'Csync' with defined circuits Instead of giving the 'Csync' with any other input pins.
