in and out impedance

Hello Jim,

The ADuM344x inputs are CMOS gates, so the impedance is high. You may wish to terminate the line externally if you're concerned about signal integrity.

The output impedance is approximately 80 ohms. Note that all AC parameters are guaranteed with a maximum 15 pF output load capacitance.

Hi Dave,

Thanks.

As for these speed higher than 100MHz, suggest to put the in/out impedance characteristic in D/S.

Regards,

Jason
