Creating a Frequency Plan for a System using a PLL

How do you ensure that every part of a system receives the clock it needs—without wasting power or sacrificing performance? The answer lies in creating a well-structured frequency plan built around a PLL.

Specifying a PLL Part 3: Jitter Budgeting for Synthesis

This white paper is aimed at system architects and physical implementation leaders working on the design of SoCs. It can be confusing to understand the impact of different jitter sources and how to calculate a jitter budget when specifying a digital system. This white paper explains how jitter changes the period of a clock and how to ensure that jitter has correctly been accounted for in the calculations for timing closure.

Specifying a PLL Part 2: Jitter Basics

This article explains a some of the key terminology and parameters commonly used to describe jitter. It will also help clarify the most important parameters for a some PLL applications, allowing the designer to better understand what is required from a PLL.

Specifying a PLL Part 1: Calculating PLL Clock Spur Requirements from ADC or DAC SFDR

In high end RF systems, such as 5G radios, the requirements are so stringent that the source of this strongest unwanted tone can be the PLL. This article outlines how spurs in the input clock to the ADC or DAC may limit the SFDR. This in turn will set the requirements for the spurs for the input clock (from a PLL), in order to achieve a specific SFDR.

Achieving Groundbreaking Performance with a Digital PLL

This article compares analog, first-generation digital, and second-generation digital PLLs. It evaluates which type of PLL may be best in which situation. It further discloses a roadmap into other application areas, including general purpose / logic clocking, and regular low-jitter PLLs.
