Pre/De-Emphasis Example

The following images demonstrate the changes that occur when pre-emphasis and de-emphasis is used in a Multi-channel eye diagram.

Note the Y-axis scaling differences.

TX waveform and Rx Eye Diagram - 6 dB Pre-Emphasis

The lower amplitude is 200 mV and the higher amplitude is 400 mV

TX waveform and Rx Eye Diagram - 6 dB De-Emphasis

The lower amplitude is 100 mV and the higher amplitude is 200 mV
