I am using the ADM3077E component in harsh environment an I am concerned about indirect lightning protection.
Is there an application note including details about lightning protection of the data ports (TVS reference example...)? What is the maximum voltage that the component can withstand on its differential ports (TX & RX) without damage?
What is the maximum resistance that could be implemented in series on the diff ports without impacting the nominal operation?
Thanks for your help.
We have a circuit note addressing your concern. I believe you will find it very helpful.
