ADC12DJ2700EVM: ADC12DJ2700EVM Lacks Documentation with my specific Board, Where Can I get my Docs?

Part Number: ADC12DJ2700EVM
Other Parts Discussed in Thread: LMK04828

I have a ADC12DJ2700EVM Evaluation Board that is of a different layout than what documentation is available on line. The online documentation which is for an ADCxxDJXX00 Evaluation Module, slau701a.pdf has a different layout than my physical board. If you look at the pdf per Figure 1-1 it shows a form factor shaped like a "T". My board is "L" shaped, Red color as well but with the dimensions on the long side of 6.25 inches, width of 3.75 inches, and on the parallel side for the 6.75 inches the other side has a notch that is 0.75 inches in size which makes it into an L shape as opposed to a "T". I suspect there is one schematic for the different Eval Boards, but I would hope there are multiple layouts and user guides. For the pdf file it shows J22  (LMKCLK) on the right hand side but for my board it is in the Center of the board near J34 and J35. So my board's layout doesn't at all agree with the documentation. Note my board has the silkscreen etch of HSP001E1. 

Where do I find the documenation for my board? Note we purchased this board several years ago and I do not have the delivered documentation.

    HI Bob,

    Sorry for the confusion. Can you please also send us a picture of the EVM and we will work to get you the proper documentation.

    Thx,

    Rob

    Unfortuanately it is in a Classified area and I don't have the ability to take a photo.

    Rob, this is an old setup that we had to resurrect. So we knew it once worked. The setup brings in a 100MHz clock into J22 which is CLKIN1 on the EVM board. I was hoping to see that LED DS3 light up and DS4 go off. These are indicative of the LM04828 selecting CLKIN1. But there were no lights on the board. I was told that power was coming in on J34 but it is labled as ADI SPI and J32 Labled as uWire. We have this connectoed to a Xilinx Eval Board which acts as the baseboard. I assumed Power was coming thru the FMC +connector but the schematic I have, HSP001-001EVM_A-sch.pdm shows no power thru that connector.

    Note the schematic block says ADC12DJ2700EVM, Dated Dec 15, 2017, with Brinkhurst as the Engineer. and Document Number is HSP001-001 Rev A. 

    Only then did I see that they did not have a power input to the +5V port on the underside left corner. Can I assume that without that +5V power feedt the LMK04828 and the LEDs will not light. Note I am pretty sure I have the wrong schematic for my board since there is no J32 or J34 connector on the schematic. Note though there is a white sticker on the board with black lettering that calls the board, ADC12DJ2700EVM. 

    Are their "L" shaped variants of this board?

    Thanks,

    Bob K.

    Hi Bob,

    Thank you for the detail. I spoke to JIm Brinkhurst and I have the files of you would still prefer those, otherwise, I can offer a new EVM and all the information you currently have would be valid.

    Please let me know which way you would like to go. We are here to support you.

    Thanks,

    Rob

    Rob, 

    Can you get me the files that document the EVM I have? 

    Thanks,

    Bob

    Hi Bob,

    Keep in mind this is a rev E1. Here is the layout, schematic and BOM.

    You will probably need an earlier Rev. of the GUI to make that board happy.

    Maybe different config files for HSDC Pro as well because the SERDES lane mapping may even be different.

    It would be easier if you start with the new/updated board. As we don't have support for this board any longer.

    Regards,

    Rob

    Rob,

    This appear to be the correct documentation that is for our Eval Board. Thanks!
