WHAT IS RC TERMINATION IN PCB DESIGN ?

In this tutorial we are going to lean about WHAT IS RC TERMINATION IN PCB DESIGN ? AC termination is recommended most for clock applications. An example of AC termination is when a 75? impedance is coupled with a 100pF capacitor. That allow for leakage in input impedance of the receiver, A resistor is selected … Read more

What is Termination in PCB?

In this tutorial we are going to learn about What is Termination in PCB?
