1.Eliminate signal reflection and ensure signal integrity. 2.Improve signal quality by reducing or eliminating ringing, overshoot, and undershoot, resulting in a clean and clear signal at the receiving end. 3.Ensure system stability by preventing random logic errors caused by reflections, enabling the digital system to operate reliably. 4.Increase bandwidth and transmission distance. Termination allows signals to be transmitted at higher frequencies over longer distances. 5.Reduce electromagnetic interference (EMI).
