Abstract

To analyze the effectiveness of various termination methods for clock traces related to signal functionality based on routed trace lengths and edge rates, the following is examined: (1) Effectiveness of termination methods which provides optimal performance for a given application; (2) Efficient termination technique for preventing ringing, overshoot and reflections; (3) Effects of various trace lengths based on clock edge rates; (4) Effects of dual (multiple) terminations. Results of this analysis are from measurements taken on a specially designed printed circuit board in the time domain. A companion paper, Analysis on the Effectiveness of Image Planes Related to Trace Lengths and Clock Edges on a Printed Circuit Board uses the same printed circuit board with radiated measurements in the frequency domain
