Can the AD72x (AD723, AD724, AD725) handle progressive video?

The datasheets contain statements like

...the AD72x requires interlaced RGB video and clock rates that are consistent with those required by the television standards.

or

...the RGB output scanning must be interlaced and at the proper scanning frequencies for either NTSC or PAL operation.

This is also mentioned in this discussion:

But it is not clear whether these statements in the datasheets are unconditional statements or whether they apply only for the case when connecting to a TV.

Best regards,

  • Hi,

     As per specification, AD725 requires interlaced RGB on its inputs & AD723/4/5 do not perform any advanced video processing, So its interlaced to interlaced.

    Note: AD725 can be used to convert the analog RGB output from a personal computer’s VGA card to the NTSC or PAL television standards.
    To accomplish this it is important to understand that the AD725 requires interlaced RGB video and clock rates that are consistent with those required by the television standards.
    In most computers the default output is a non-interlaced RGB signal at a frame rate higher than used by either NTSC or PAL.

    Thanks,
