12.4 PCB trace impedance matching

설명

2022년 3월 8일

In this video we will discuss how the PCB trace characteristic impedance is determined by its geometry.  We will see how matching the driver to trace impedance can impact the rise time, overshoot, and ringing on digital communications signals.  This is important because the overshoot and ringing can create noise problems that impacts sensitive analog and, in some cases, can even cause digital communications issues.
