• ADV7625 RGB 4:4:4 Color Space Issue

    I started this question with my original post: ADV7627 RGB 4:4:4 Color Space Issue 

    Colorspace continues to plague my system and I am looking for some guidance. I have spent a considerable amount of time looking at the AVIAPI routines but there are some…

  • Any SDTV Video Decoder with 4:4:4 output?

    Hi we are looking for a video decoder which can convert PAL/NTSC composite, S-Video and YPrPb.
    Output format doesn't matter, it can be YCrCb 4:4:4 or RGB (it will go to FPGA so we can do any conversion).
    However all SDTV decoders I found only produce…

  • ADV7181B RGB 4:4:4 640 x 480i configuration

    To digitize RGB, 4:4:4, 640 x 480i, square pixel video at a 30Hz frame rate please confirm the following.

     

    ·         Need a 28.63636MHz, < 50ppm crystal

    ·         Table 21 in the user manual shows NTSC square pixel format is supported. Is the square pixel format…

  • ADV7342/7343, SD only, 24bit, 4:4:4 RGB input

    Hi,

    Our customer is asking whether ADV7342/7343 can handle video input of SD only, 24-bit, 4:4:4, RGB pixel input as shown in following timing.

    It is a bit different from timing shown in Datasheet Figure 4 as follows, that it has 122 clocks interval…

  • ADV7181D 12 bit RGB 4:4:4 DDR mode

    On this mode, half of the data is sent on the rising edge of the LLC clock, and the other half is on the falling edge. Assuming the video source is 525i RGB with SOG (SD) the LLC clock is 27Mhz, or 2X the pixel rate. Does this mean that every RGB 12 bit…

  • On EVAL-CN0313 there are three different circuits that offer various protection levels for IEC61000-4-2 ESD, IEC61000-4-4 EFT and IEC61000-4-5 Surge. Why is there different protection circuitry used for Surge Level 4 compared ESD/EFT level 4?

    The EVAL-CN0313SDPZ is a certified EMC Compliant RS-485 Interface Design Tool. 

    The main reason for the different protection circuitry is related to the difference in energy levels associated with each of the transient waveforms. According to the IEC61000…

  • [ADM3491-1] what difference between IEC1000-4-4 and IEC610004-4?

    Hello,

    According to ADM3491-1 datasheet, this part  " Meets IEC1000-4-4" as below,

    What difference between IEC1000-4-4 and IEC610004-4?

    IEC61000-4-4 covered IEC10004-4?

    Thank you for your help in advance.

    Best regards,

  • Register settings for ADV7511 with 4:4:4 RGB or YCbCr

    I've been using the ADV7511 with 4:2:2 but are adding 4:4:4 RGB and 4:4:4 YCbCr modes but the output video has faint vertical lines across the image when I send data that ramps.  Normal video shows random data value shifts that seem to be more prevalent…

  • ADV7513 12-bit RGB 4:4:4 DDR input in DVI Mode

    Is it possible to drive the ADV7513 with 12-bit RGB 4:4:4 in DDR mode?

    The Programming Guide Page34, refers to an Input ID=0101, but there is no further reference for the mapping of these 12 bits on the input data lines D[23:0].

    There is no reference…
