Using Mixed Signal Oscilloscopes to Find and Diagnose Jitter Caused by Power Integrity Problems

Learn about the connection between signal integrity on data and clock lines, and power integrity.  This application note gives a brief review of jitter measurements and terminology, including eye diagrams and jitter decomposition. It describes types of noise that impact power integrity, with special attention to power rail noise likely to cause jitter.  It includes a measurement example showing the impact of ripple on a power rail tied to jitter on a clock signal.
