When working with high frequency switching waveforms, loop inductances need to be minimized to keep ringing at a minimum. Loop inductances can arise due to component placement and routing. Place traces along the shortest distance between components and integrate bypass capacitors into the design to maintain signal integrity.
Trace length and placement need to be taken into consideration when routing. Short, straight traces produce the lowest impedance path for the signal and minimize the current loop area, thereby reducing loop inductances present.
Bypass capacitors filter and condition signals before use and place as close to the respective component as possible. Any extraneous trace between the capacitor and component mitigates the effectiveness of the bypass capacitor.
