After my general questions about how to setup the ADV7611 I've done some testing.

The source video format is 720p50. I'm using the ADV7612 Evalboard. I want to output a 16-bit ITU.

My configurations are:

VID_STD 0x13


Register 0x02 has value 0xF5


Register 0x04 has value 0x62

Register 0x05 has value 0x20

Register 0x06 has value 0xAE


So I guess the basic configuration should be fine.

Now I took a look at the output signals. Attached are the measurements. As you can see, there are some gaps within the clock. They appear around every 500ms. Is this behaviour a normal one? If not what could case the clock to akt like this?

Beside this, does the other signals look like they are suppose?


I just want to make sure my configurations are fine and the output is as it should be.
