• JPEG Processing - 4:2:2 v 4:2:0?

    My JPEG saga continue...

    I am using a BF561 single core to compress a 640x480 YUV 4:2:2 image into JPEG format, employing the ADI JPEG Library tools.  I am getting very poor performance compared with the reference results from the Spec Sheet.  The Spec…

    Hello Dave,

    I am facing problems with replies to your answer, so I am oppening a new dicussion with the same title.

    Please clarify your answer regarding STANAG support:

    2) As I understand it, this is the same as RS-343A/EIA-343A and none of our parts…

  • LTC6804-2 and LTC6811-2 reference voltage 1 and 2 at 0V.

    Hello,

    I installed 2x LTC6811-2 and then 1x LTC6804-2 on the same board and I don't have any voltage reference output at anytime. The functional diagram in the datasheets shows that VREF1 should be always present as it's generated from V+. VREF2 is not…

  • RE: Clock distribution to 2 DDSs (9913) and 2 ADCs (AD7769)

    Hi,

    the AD9577 is a good choice if the 40 MHz clocks to the AD9913 may not be phase aligned to the 40 MHz clocks to the AD7769.

    The AD9577 has two PLLs that are not recommended to work at the same frequency because  the jitter performance is degraded …

  • 2*2 MIMO setup

    Hello,

    Iam interested in implementing a MIMO 2*2 scenario where i will use 2 fpgas (1 as the transmitter and 1 as the receiver) where each one  will be connected with one AD-FMCOMMS3-EBZ.
    So the setup will be :
    FPGA_1 + AD-FMCOMMS3-EBZ_1 =Base stati…

  • ADV7403 YUV 4:2:2?

    Can the ADV7403 output YUV 4:2:2 rather than YCbCr 4:2:2?

    Thanks.

    Hi,

    I have the EVAL-ADV7612-7511p video evaluation board .I'm using 7612 to receive  HDMI inputs from camera(720p @60) , and then feed to 7511 to output the video to the screen.

    When adv7612 output 4:4:4 8bit ycrcb…

  • ADV7610 registers 4:2:2

    Hello

    Thanks in advance.

    I have a input video signal whose format is: YCbCr (Digital YUV) 20 bit (10 chroma + 10 luma).. 1080p60 (1920x1080 60 fps).

    As I can read in this forum ADV7610 only supports four modes for SDR 4:2:2:

  • YCbCr 4:2:2/12 ADV7619

    When I input YCbCr 4:2:2/12 into my ADV7619 and readi back 0x0B(DEEP_COLOR_MODE) of the HDMI map it always reports 8 bits per channel.  I also see this on the eval board as well.  While YCbCr 4:2:2/10 is reported correctly.

    Is there some conversion in…
