Is this device received AC coupling?

I would like to connect AC coupling to input and output.

    Hello,

    you need to externally ac couple the signals.

    Regards.

    Hello,

    we plan to mux externally AC coupled signals up to 5GHz over HD3SS3412.

    When VIO_DIFF = 1.0V and VIO_CM = 0.0V, we are a bit concerned about the negative swing of -0.5V being at the absolute maximum rating of differential IO.

    Is it recommended to adjust VIO_CM with a resistor network or can we do without due to parasitic impedances?

    Advice very welcome, thanks.

    Best regards

    Hello,

    There should be no issue, the recommendation is to populate a place holder for the biasing resistor.

    Regards.
