Phase Noise Aliases as TIE Jitter

Here’s a look at how phase noise converts to time-interval error jitter, which is particularly important to those working on reference clocks for high-speed SERDES or sampling clocks. Read on to see how this can help debug systems to reduce sources of timing noise.

Measuring Phase Noise with Baluns

Differential clock and timing devices are commonly characterized for phase noise using baluns. While deceptively simple to use, baluns perform a fairly complicated process that can unknowingly introduce artifacts into measured results. This article describes such artifacts, discusses why they appear and how to eliminate them. Recommendations are provided for selecting a balun and using it to accurately characterize devices for phase noise.
