Thank you so much for such great video and explanation. you covererd many of my doubt but still left with some like why special interfaces have different characteristic impedance and how to know them and how to set them Im talking about RJ45 . I know on youtube there are videos available where people open stackup manager and put random value but i want why i want to known how this things really works
@moneshrathod, I'm glad you enjoyed the video. Thank you for watching it. The short answer: To determine the characteristic impedance required for different interfaces, usually, a quick internet search will provide you with the result for the most common ones. Twisted-pair Ethernet cables present a characteristic impedance to the receivers and transmitters at the RJ45 plugs. Typically, this impedance is 100 ohms (Ω) and needs to be consistent along the length of the cable. When you are designing your own circuit, though, you will usually find this information in the datasheet of the component or integrated circuit you are using. Hope this helps. Dario P.S. I will try to create more in-depth content explaining why there are different requirements depending on the interface you use.

Brilliant video. I did not know these things about impedance. Thank you for this education. I subscribe now.
