The ability to understand, identify and solve serious jitter problems is imperative as data rates exceed the Gb/s level. From SONet/SDH networks at OC 768—nearly 40 Gb/s—to Gigabit Ethernet and 10 Gigabit Ethernet, low data rate jitter analysis techniques that use real-time data acquisition such as Time Interval Analysis (TIA), cycle-to-cycle, and period jitter analysis are less useful. At high data rates techniques like low noise phase detection, high speed sampling, and indirect analysis methods are necessary.

This paper includes a concise description of jitter and the primary issues in jitter analysis at high data rates, details the five analysis techniques, and distinguishes the techniques from one another and offers recommendations for their application.
