Clocking 101

Timing Expert Sieg Schmalz shares how our relationships with clocks change when looking at them through the lens of timing applications.

Rob Jodrie – 3rd Generation BITS Part 1-3

Rob Jodrie has been supporting Network Timing for over 20 years. In that time, he’s seen the 1st Generation BITS progress to the current and new iteration known as 3rd Generation BITS. In this video, Rob goes into detail on each generation and shows you how we evolved to today’s BITS clocks and their capabilities.

Rob Jodrie – 1st Generation BITS Part 1

Rob Jodrie explores the beginnings of BITS technology known as 1st Generation BITS. It’s part of a larger presentation that includes 2nd and 3rd Generation BITS capabilities and benefits.

TimeProvider® 4100

TimeProvider® 4100 is a gateway clock, a new class of synchronization product that accepts multiple inputs from Global Navigation Satellite Systems (GNSS), Synchronous Ethernet (SynE), and 1588 PTP Grandmaster Clock and E1/T1 digital transmission links, and distributes timing flows to multiple end points such as base stations.

GPS Vulnerability Support With BlueSky GNSS Firewall

BlueSky GNSS Firewall protects deployed GNSS systems by providing a cost-effective overlay solution installed between existing GNSS antennas and GNSS systems. The BlueSky GNSS Firewall protects systems inside the firewall from untrusted sky-based signals outside the firewall.

vPRTC

The virtual Primary Reference Time Clock is a highly resilient timing architecture that reduces reliance on Global Navigation Satellite System (GNSS)-based timing signals.

Sieg Schmalz discusses the relationship between Frequency and Phase, as well as how to quantify Phase Error and Frequency Error.

Sieg Schmalz explores Frequency Stability, how to quantify it, and provides some examples to illustrate the concept. For more information, visit our Clock and Timing product page:

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. For more information, visit our Clock and Timing product page

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. For more information, visit our Clock and Timing product page:

What are phase noise and ADEV and why are they important? In this tutorial, we will explain the basics of what phase noise is, why it is important to consider in your designs, and draw out some examples of its application. We’ll also show how the 53100A measures phase noise, jitter and other important performance characteristics.

Phase Power Spectral Density — more commonly called “Phase Noise” in Timing applications – is explained in this video and compared to FM radio modulation. Phase Noise refers to the undesired frequency/phase deviations of a clock signal from its ideal frequency, and it is a critically important parameter in data communications; if Phase Noise is too high, it can cause data errors.

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.

Timing specifications typically include parameters such as “Phase Noise” and “Jitter”, which are related to a clock’s Phase Domain Spectral Power Density. This video reviews Voltage Domain Spectral Power and Spectral Power Density, which lay the groundwork for understanding Phase Domain Spectral Power Density.
