Hi Gents,
What is the input/output impedance of Adum3441? It's for high speed so I want to make sure it's 50 ohms.
Thanks
Jim

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.
