Hi,

I am goning to distribute a common 40 MHz clock to 2 DDSs and 2 ADCs. Will AD9577 work for this purpose? If not, do you have any suggestion?

The ADC needs 5 V CLK and the DDS needs 1.8 V CLK.

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:

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…

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…

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. 

camera -> 7612 --> 7511 --> screen

When adv7612 output 4:4:4 8bit ycrcb…

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:

                 - 8 bit SDR ITU-R BT.656…

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…

The windows application auto calculates the negative bleed current, even if FRAC1 and FRAC2 are not 0, but from the ADF4355-2 Rev C page 25, :

"Use negative bleed only when operating in fractional-N mode,
that is, FRAC1 = FRAC2 = 0. Do not use negative…
