The Research on Emphasis Techniques for Optimizing Signal Quality in SerDes System

With the increase of data transmission rate, SerDes system is widely used in high-speed communication. However, signal attenuation and noise interference are the key factors affecting its performance. This paper studies the application of the key technology in the SerDes system, and evaluates the influence of pre-emphasis and de-emphasis on signal quality by eye diagram analysis. The experimental results show that the Jitter value of the noisy signal is reduced by 71.3% after applying de-emphasis technology compared with the case without de-emphasis technology. The effectiveness of the weighting technique in improving the transmission quality and reducing the bit error rate is demonstrated.
