Digital Timing: Clock Signals, Jitter, Hystereisis, and Eye Diagrams

Updated Apr 19, 2023

Overview

Learn about digital timing of clock signals and common terminology such as jitter, drift, rise and fall time, settling time, hysteresis, and eye diagrams.

This white paper is part of our Instrument Fundamentals Series.


Topics Covered

  • Clock Signals: period, duty cycle, active clock edge, rising edge, falling edge, setup time, hold time, aberrations, preshoot, overshoot, undershoot,
  • Common terms: jitter, drift, rise time, settling time, hysteresis, skew
  • Eye diagrams: high level, low level, amplitude, bit period, eye height, eye width, eye crossing percentage, rise time, fall time, distortion, signal-to-noise ratio, jitter, best time to sample
