I'd like to make a simple YPbPr 1080i50 test pattern generator using the ADV7393, but have a few questions that I'm hoping someone can answer.
When using the internal test pattern generator on this device, what are the timing options available? Can the device generate it's own HVF if I provide it with just a 74.25MHz clock and set the 16bit input bus to 0, or must I also provide sync signals to the HSYNC & VSYNC pins? Can one provide the sync through embedded TRS when using the internal TPG in HD?
Also, am I correct in thinking that although the current version of the datasheet states clearly on both page 1 and page 79 that this device can internally generate an HD colour bar signal, in reality the ADV7393 CANNOT actually generate HD colour bars?
And finally, what is the luma output range of the internally generated HD black bars - can it be set up to give the full 700mV range?
