Abstract

Disclosed is the method to avoid serial data transfer error between modules on a PCB. As LSI technology is getting faster, rising time and falling time of the waveform from the LSI is getting faster. That means increase of reflection and crosstalk. If the distortion of the waveform caused by the reflection and the crosstalk goes over a logic threshold
