• AD723,AD725,AD725 RGB inputs

    I read in all of these datasheets that the AD723,AD725, and AD725 all require interlaced inputs. If I want to feed a  pc's vga output into one of these IC's, would these still convert the RGB to composite? Are there other solutions from Analog Devices…

  • AD725 RGB to Composite Video Converter Issue

    Hi !

    I am using AD725 for converting RGB analog video to composite video. I am providing my personal PC output to the input pins of AD725 but the result that I am getting is 3 frames in one picture (Picture of the composite video monitor is attached)…

  • AD725

    Dear support team

    From one of my customers: 

    We have used the AD725 to convert PC VGA to composite analog PAL video.

    This design is based on AD725 data sheet schematic (page 12).

    It seems that the PC is output a VGA non-interlace data , so this device…

  • AD725 Spec

    Hi ,

    Could you please let me know if AD725 can output Mono Color (RS-170) with out Color burst .

    If AD725 cannot do this is there any other device which is suitable to do this .

    Thanking you

    With best regards and wishes

  • AD725 issues

    We have an ongoing project which is using ivy bridge + QM77 platform + AD725. The system equipped with on TVOUT(NTSC) by extract analog signal from standard VGA output. Following picture is the result of display.

    Unfortunately, I checked the datasheet…

  • about AD725

    Now we use AD725 to change VGA signal to PAL signal.I have a question:can AD725 support maximum resolution of 1600×1200@60hz,if it can not support,what is the maximum resolution of VGA signal input?

  • AD725- Hsync input

    Hi,

    I am extracting the Composite sync by using EL1881 and the extracted composite sync is applied to AD725 Hsync input pin.

    By using AD725 i am generating composite video output and S-Video output (by separate chips )from individual RGB sources.

  • AD725 colour problem

    Hi,

    We are using AD725 IC to get PAL composite video output. The input to AD725 is RGB (576i) interlaced output from ADV7123 IC generated from FPGA. We are seeing color problem and flickering on the composite output. Attached are the snapshots of the…

  • AD725 outputs wrong colors

    I designed device based on AD725ARZ. Device is built basing on the reference circuit diagram on page 12.

    TV is connected to **composite output of the circuit**. It does not have S-video input, thus no way to test the S-video image (at least for now).
