Timing specifications typically include parameters such as "Phase Noise" and "Jitter", which are related to a clock's Phase Domain Spectral Power Density.

Engineers are typically accustomed to thinking in the Voltage Domain, but to understand Timing, one needs to understand how to think in the Phase Domain.

Phase Power Spectral Density -- more commonly called “Phase Noise” in Timing applications – is explained in this video and compared to FM radio modulation.

This video describes how phase noise is measured and how these measurements are used to determine whether a clock meets phase noise mask specifications for a given device.

This video explores Time Interval Error (TIE), the deviation between a real clock's rising edge and an ideal clock's edge.

Microchip’s Expert Sieg Schmalz describes some of the other parameters that engineers use to determine whether a clock is a good fit for a given application. These parameters include rise and fall time, slew rate, duty cycle, propagation delay, skew.

The video explains the relationship between Time Interval Error (TIE) and Phase Noise plots, illustrating how phase noise at specific frequency offsets represents the combined phase power of clock edges.

Microchip’s expert Sieg Schmalz explores Frequency Stability, how to quantify it, and provides some examples to illustrate the concept.

Microchip’s Expert Sieg Schmalz contrasts stability vs. average value and stability vs. accuracy. He also explains how these parameters are described in a typical Timing Source data-sheet.

Microchip’s expert Sieg Schmalz provides a definition of Clock Phase as it pertains to timing applications and provides some examples of describing phase.
