A low cost asynchronous eye diagram reconstruction system for high speed links

As link communication data rate increases, there is an increasing need for a more cost eective way to test and monitor signal integrity in link communication systems. Specifically, eye diagrams are valuable visual aids to analyze and quantify digital signal quality. This thesis presents a novel low cost eye diagram reconstruction system using asynchronous undersampling technique, which solves a key problem in performance monitoring in systems where synchronous sampling is not available, such as video switches. Existing works are studied and compared to this work in performance and cost. The proposed system is designed as a system-on-chip (SOC) and contains an undersampling ADC, aliased frequency estimator and a simple reconstruction algorithm. Major building blocks are implemented and simulated in 65nm CMOS process. Extensive system level analysis and simulations demonstrate functionality and performance of the system working at 10Gb/s maximum data rate.
