Video Clocked Input

Hi all, I am reading data from OV7670. I want to use Video Clocked Input to convert clocked video to streaming video, then store it to DDR3 SDRAM through Frame Buffer. OV7670's signals are PLCK(...

Hi,

You have to know the format of your video (for example I use YCbYCr 4:2:2, which is 8 bit per color plane, 2 color planes in sequence so 1 parallel).

In my example vid_data will be a bus of 8 bit, and I will attach there my clocked video. The hsync and vsync are obviously the syncs, I think they are your HREF and VSYNC.

Finally I have always tied vid_datavalid to VCC.

I don't know a lot about OV7670, but looking very quickly its datasheet it seems that it will give you video data already good for CVI.

Bye
