Noise Suppression DLP/DLW Series Example
Mechanism of Skew Improvement Waveform rises (or falls)
Example of Skew Improvement by Common Mode Choke Coil (Test using pulse generator waveform) Waveform is equivalent to 1000Mbps signal
Waveform with intentionally made skew (skew: 100ps) Skew is improved by common mode choke coil
Current change generates magnetic flux on a ferrite core
Electromotive force is generated on another line
