ADS54J64EVM: Connecting to KC705

Part Number: ADS54J64EVM
Other Parts Discussed in Thread: ADS54J64, ADS54J66EVM

Hi,

I'm considering buying a ADS54J64EVM board, to be used directly with a KC705 and possibly a third-party JESD204B IP core for high-speed data acquisition and processing, but I have a few questions:

A) Are the boards compatible? From what I saw in the schematics for the ADS54J64EVM it seems so, but I would like to be sure before buying (and I'm not particularly familiar with JESD204 yet). I understand that the KC705 has a limited number of high-speed transceivers available on the FMC HPC connector, which can pose a problem.

B) If they can be connected, would I be able to use all the features of the ADS54J64 (eg. all 4 channels)? If not, which features would I lose?

C) What kind of support (in the form of example projects, code and IP cores) is provided for this kind of setup?

Best Regards,

Laez

    Laez,

    You should be able to operate all 4 channels of the ADS54J64EVM with the KC705. We have tested the KC705 with an ADS54J66EVM using a TI interposer board called the TSW14J10EVM. The ADS54J66EVM uses the same PCB as the ADS54J64EVM. Example firmware for this can be found under the TSW14J10EVM product folder on the TI website. Attached is a setup document showing how to run the three boards together. 

    Regards,

    Jim,

    Thank you very much for the quick response. It's good to know that the boards are compatible, and that I would not lose any functionality. However, the documents you suggested are all for setups using the interposer board, and I would like to connect the two directly. Are you suggesting that I should start from the interposer design in order to develop my own?

    Thank you,

    Laez

    Laez,

    The ADC EVM will plug directly into the KC705. This is what you would do if your were generating your own firmware. We developed the TSW14J10EVM to allow customers to evaluate these boards using our HSDC Pro GUI software. This GUI was designed to work on our Altera based evaluation boards but the TSW14J10 allows the user to use this GUI with many different Xilinx boards. We provide the source code that was used for this to help customers get a head start with their custom design. Hope this makes sense.

    Regards,

    Jim
