• RE: ADV7441A calculation of pll charge pump current

    Hello again,

    is for ADV7441A an Excel Sheet for PLL calculation available like AD9888 / AD9884?

    Thank you for your answer.

    best regards

  • RE: TFT-Monitor Interface: VGA / DVI In, LVDS out

    So the system would look like this:

    some kind of buffer amplifier for RGB analog in, then one of the HDMI controllers such as AD9888 and then an LVDS driver circuit plus a microcontroller for settings.

    What about OSD menus: how to accomplish this ?

  • RE: ADV7604 and video with one long line

    Hi Curt,

    Dave has asked me to have a look at this issue for you.

    I'll have a dig into whether it is possible for us to make ADV7604 behave more like the AD9888.

    Will send you an update in a day or two.

    Regards,

  • RE: AD9983A noise

    Hi Christophe,

    It seems like AD9888 is not recommended for new designs. We should probably stick with AD9983A.

    I talked with our AD9983A expert and he was puzzled about why the blue channel would be giving you trouble. Any additional debug information…

  • How could correct the VGA gray color

    Hi

    we used the ad9888 as the video A/D in fornt end .

    input source is the VGA , and has the 60% rate IC has the gray color.

    we tried change the part and find that it following the part.

    So, we think must colloct the vga's ADC offset.

    but how…

  • RE: ADV7604 Analog Component video standard selection logic.

    Hi Dave,

         Yes, I'm looking at it now.  I'm using the ADV7604 to upgrade an old design using the AD9888 where originally I measured the raw syncs within my GPU.  I'm at a point where I'm assesing how much of my old GPU & video mode database settings…
