I'm trying to use an ADV7393 Encoder to generate a color bar pattern for testing purposes. The pattern shows up, but without color. I'm using ADV Register Control 3.56 to modify the registers according to Table 60 of the datasheet for Composite video on DAC1 output(all other registers are set to their default values):
The color carrier appears in the signal and is at the right frequency (3.57MHz):
I'm a little stumped. The color carrier is present and at the right frequency but I am getting this on the display:
I've verified the display with a NTSC generator. I was wondering if there was a register setting I'm missing; is this a known issue? Any help would be appreciated.
