The post-Covid era has enjoyed an unprecedented rise in high bandwidth consumption activities such as remote working, streaming, VR, and AR. With the recent breakthroughs in AI and introduction of ChatGPT, data transport and interconnect fabrics of data centers are being stressed to the limits and forced to scale up even more rapidly than their traditional pace, leading to design reconsiderations on many fronts. In this talk, we revisit historical wireline trends in the last 20 years and their challenges, as well as give Marvell success stories on how these new frontiers are being tackled.


Ray Nguyen received his BS from the University of Texas at Austin in 2006, his MS and PhD from Stanford University in 2008 and 2011, respectively. His dissertation focused on high-speed parametric pipeline ADCs and their compensation techniques. He joined Clariphy Communication in 2012, which was later acquired by Inphi in 2016, and subsequently by Marvell in 2020. In the past decade, Dr. Nguyen has built and led various highs-peed serdes and optical projects with state-of-the-art performance from inception to production. His research interests include highspeed analog front-end, time-interleaved data converters, digital signal processing, and calibration techniques. He authored over a dozen US patents and publications and currently serves as a sr. Principal Engineer at Marvell.

Arik Zafrany received his B.Sc  and M.Sc degrees in electrical engineering from Tel-Aviv University, Israel in 2001 and 2004 respectively. His master degree dissertation focused on solitons in a linearly coupled systems with separated dispersion and nonlinearity. He has worked on communication circuits for wireless, wireline and fiber optics applications and is currently with Marvell semiconductors working on high-speed circuits for fiber optics applications.
