• 最爱ADI放大器-ADA4692-2

    我们的变送器产品中用到放大器芯片对传感器探头信号进行预处理，因为是4...20mA接口，因此需要低功耗的放大器芯片。我们就选择了ADI的放大器ADA4692-2.

  • Voltage follower on ADA4692 cut of the signal

    I try to create simple voltage follower on ADA4692 but there was a surprise. In some reason it cut of the signal. In any follower shemes. I try all possible shemes. If I tied input to Vcc (3V) the output is still on cutt-of position (near 2V). Any other…

  • 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…

  • ADV7842 4:2:2 DDR mode, ADV7393: Stanag3350 support?  (2)

    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.
