Title: Introduction to DSP based Serial Links
Speaker: Fernando De Bernardinis, eSilicon

Abstract:
We introduce the design challenge of implementing a Serializer/Deserialized (SerDes) system capable 
of sustaining a bitrate >50 Gb/s and 100Gb/s. The switch from an NRZ to a PAM-4 modulation scheme, 
with the increased equalization power required on the receive side, encourages the adoption of DSP 
based solutions to implement current and next generations long reach SerDes. There are two big 
challenges to be coped with, power consumption due to digital domain signal processing, and the 
complexity of designing the Analog Front End capable of converting A/D and D/A at the required 
sampling frequency. A holistic approach implying the codesign of the AFE and DSP, including an 
embedded software component as firmware, has been taken to provide a very efficient and powerful 
implementation in 7nm. Given the complexity of the system, the software component provides crucial 
control and configuration tasks, which include setup and optimization of the link for different 
communication speeds and modulation, as well as link monitoring and exception handling. The embedded 
nature of the application implies limited resource availability and tight interaction with analog 
and digital circuitry, which makes development and testing a team work with designers and test 
engineers. Finally, some details of the architecture and performance as presented at this year’s 
ISSCC are given, showing how both power consumption and channel length are widely improved over 
previous works.

Speaker's Bio:
Fernando De Bernardinis received the Laurea degree in electrical engineering from the University of 
Pisa, Scuola S. Anna, Italy, in 1996, a Ph.D in Electrical Engineering from the same University in 
2000 and M.S. and Ph.D. degrees from the University of California, Berkeley, in 2001 and 2005, 
respectively. He was Assistant Professor in the Department of Information Engineering at the 
University of Pisa until he joined Marvell Italy in 2006 and eSilicon in 2017. His research 
interests include digitally assisted analog design, mixed signal system level design, architecture 
design and DSP algorithm optimization. Since 2012, he has been leading the architecture and 
algorithm design of DSP based serial links, developing 56 Gb/s and 112Gb/s generations at eSilicon.
