• AD723 Input Resolution and format support

    We are using DM388 SOC Display out which is connected to AD723 Encoder

    What are the supported input resoltion for AD723?

    We are Valitated the RGB out from DM388 to VGA conncetor it working fine.

    The same RGB passed to AD723 for S-video conversion but…

  • The color burst from AD723 seems to move on AD723 Eval Board.

    Hello,

    I have questions about AD723.
    The start point of color burst from AD723 seems to move on AD723 Eval Board (AD723EB rev.B).
    Could you see attached file "Color_burst_AD723_rev01.xlsx" for more detail?

    Thank you!

    Best regards.

  • ADV7123

    I have one color video signal (RGB 24 bits) and another monochrome video signal (8 bits).
    I want to obtain a PAL video signal from each of these signals. I am using the ADV7123 DAC, and the AD723 encoder.
  • RE: ADV7123 Interlaced support

    I did this with AD7123 and AD723. It works. I even have implemented two oscillators to obtain PAL and NTSC and switch between them thru some logic. I used the composite sync from the AD7123 input, which I generate by the FPGA, also in a buffered form…

  • RE: We need "SYNC SEPARATOR" block diagrams of AD723.

    Is this related to thread http://ez.analog.com/message/88784#88784 ?

    I'm am contacting the AD723 expert for more information.

  • 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…

  • AD723 Schematics & clarifications

    My customer needs an RGB to PAL/NTSC converter. AD723 should be a good option but seems very old, Eval board working with DOS and win95... Is there a newer part?  If no where can I find the design package for it?

    Where can I find an updated schematic…

  • AD723 input range

    I am using AD723 from analog device in one of my design.

    The above mentioned part is a analog RGB to NTSC/PAL converter.

    Could anyone please let me know the acceptable input RGB resolution range for the part?

    640 x 480

    800 x 600

    Etc..

  • AD723 Colors appear wrong

    I am driving an AD723 with the output of a triple RGB DAC which is being driven by the digital RGB outputs of an LCD display driver.  When I ramp the R, G and B outputs with test patterns, I see those colors go from dark to bright as expected.  However…

  • RE: Composite video encoding

    Hi John,

    The AD723/4/5 require interlaced RGB inputs, so this is something to consider as well.  Please feel free to contact me directly if you have further questions about the encoders.

    Best regards.
