Dear Ti support,

in the ADS4122 Datasheet it is suggested to select "mode 2" to enhance the performance for input frequencies above 230MHz (Register address = 4Ah, register data = 01h ).

What does this enhancement actually mean? what happens by selecting this mode? It would be great to get some hints for understanding, as this seems the only (possibly good, possibly not good) reason why we should change ADC configuration via SPI.

Thank you.

Best regards,

  • Hi Paolo,

    Unfortunately, we do not have an EVM in the lab so I am unable to simply check what this feature does. I will check with Jim to see if he has heard back from design. Apologies for the delay in answering your question. If a thread is locked due to inactivity, please just use a link to reference the previous thread as copy/paste makes this hard to follow.

    Regards

  • Hi Paolo,

    Unfortunaately, we do not have an EVM from this device family in the lab so I am unable to quickly check this for you. I will check with Jim to see if he has heard back from design. In the future, please only use a link to reference an old thread as copy/paste makes everything hard to follow.

    Regards

  • Paolo,

    Not sure why the post got blocked. We are still waiting to hear from the design team about this question. Sorry for the delay.

    Regards,

    Jim
