Maximizing Performance and Reliability of SERDES Interfaces

Understanding and optimizing SERDES Interfaces


This Fidus whitepaper, awarded the Outstanding Paper Award at EDI CON USA 2017, delves into the complexities of high-speed SERDES (Serializer/Deserializer) interfaces, particularly focusing on their implementation on single printed circuit boards and backplane systems. With data rates exceeding 5 Gbps, these interfaces have become commonplace, but ensuring error-free operation remains a challenge.

This paper explores the design process, emphasizing the importance of understanding parameters like s-parameters, insertion loss, return loss, skew, and insertion loss deviation. It also addresses the impact of ground plane resonance and skew between differential pairs on link performance.
