Hi Expert,

I wonder to know how can I make sure the ZO value as pic?

Is that just a simulation value or calculate result ? if so , please provide the formula or calculate tool.

If it can be measurement , could you please share more detail how to set up and get the correct result.

And the TPS65994 EVM will impact some final result for Zo ?

    Hi Eddie, 

    Can you send me the file/presentation where you got this information from? 

    Also what is the purpose for this ask? Are there concerns with the line impedance on TPS65994EVM? Where exactly is the impedance being measured? 

    Thanks and Regards,
