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.

Thank you for the replay.

I need to V-by-One signals.

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.
