Thermal sensors generate the progressive video at a resolution of 640*480 and according to the ADV7340/ADV7341 datasheet, the video must be in an interlaced format to convert digital video of resolution 640*480 to analog video how to generate the analog output (NTSC and PAL) if the digital input is a progressive video of 640*480 by ADV7340/ADV7341 IP.

    Hi,
    

    ADV8005/ADV8003 is the only part which can support scaling as well as P to I conversation.
    

    This attached file ez.analog.com/.../adv739x-design-support-filesWhich ADV739x video encoder should I choose compares all members of the ADV734X and ADV739X series of parts.These are the latest video encoder parts on offer from ADI .
    

    Note: ADV7340/ADV7341 support an SD noninterlaced mode. Using this mode, progressive inputs at twice the frame rate of NTSC and PAL (240p/59.94 Hz and 288p/50 Hz, respectively) can be input into the ADV7340/ADV7341. The SD noninterlaced mode can be enabled using Subaddress 0x88 Bit 1. For more details please refer Page56 at ADV734x datasheet.
    

    

    Thanks,
    

    Poornima
