ADV7125 with i.mx6

Hi, I'm trying to combine i.mx6 and ADV7125 to get RS170 output

I mean 24bit RGB data from i.mx6 will enter to ADV7125 input 

But I'm not sure that ADV7125 can catch 24bit RGB data format(1024 x 768, from i.mx6) and source RS170 signal(640 x 480 format)

Is there anyone which can solve this issue?
