[TVP7002] output a wrong Data Enable singal

i want to use it to converter VESA standard 5 wire PC graphic (1280x720@60)in to BT 709 YCbCr .

I check the recommend documents and setted the register

I get some singal with right pixel frequence right H, right V and a wrong DE which is 43KHz (I just want 30Hz)

what should i do?

can you give me some suggestion?

  • DE is a line based signal so it will be in the KHz range.

    DE qualifies the active pixel data and will be active only for the active pixels on each line, then go inactive for the horizontal blanking period.

    If you need a signal at the frame rate then look at VSync.

    BR,
