TMDS64DC01EVM: missing breakout pinning info

Part Number: TMDS64DC01EVM

Dear TI,

where is the detailed pinning of breakout connectors? it is neither availabel in SPRUJ06 User's Guide not in your web site.

Regards, Kalman

  • Hi Kalman,

    Perhaps I'm misunderstanding your question but the HSE connector pin mapping is available in section "3.3.4 Board Mating Connections" of the User Guide. Otherwise, the pinout of the SoC is available on the processor product page along with the board schematics and other design files. 

    Regards,

    Andrei

  • Hi Andrei,

    yes I have found Table 3-4 in chapter 3.3.4 of SPRUJ06. But I would like to see the signals on J2..J9 connectors. Table 3-3 lists the signals and mention test headers without pin numbers!

    And I have not found circuit drawing of TMDS64DC01EVM on ti.com. I miss pinning of J2..J9 connectors.

    Regards, Kalman

  • Hi Kalman,

    I understand the confusion, let me explain, 

    The pins are listed as they are laid out top to bottom on one side of the connector (the "odd" numbered pins) while the other side of the connector (even) is always Ground. 

    Here is an example for J7. All the other connections follow the same convention. 

    And here is a matching example for J2 to hopefully make it clear:

      

    I appreciate the feedback that Table 3-3 is potentially confusing. I've added a change note for the next revision of the user guide and the product page will be updated accordingly with the design files in the near future.

    I have checked and the table IS consistent with the schematic, so that should not be cause for concern. 

    Best Regards,

    Andrei 

  • Hi Andrei,

    thanks for your response, that is what I need.

    Would you so kind to check my table (and fill it up), please?

    Or could you attach the other connectors from the circuit drawing?

  • Hi Kalman,

    I've checked and it looks like I was also misinterpreting that table and how it's arranged. I've checked against the schematic and the following is the corrected signals from your table:

    The document will be updated soon to include proper tables for the connectors and I've added the task of getting the design files on the product page to my queue.
