Tutorials & Webcasts
Fundamentals of Frequency Synthesis, Part 1: Phase Locked Loops
The first of a two-part series on frequency synthesis, with an introduction to Phase Locked Loops. This webcast looks at the need for frequency generation, the techniques from the past present and future, and how to assess the performance of a frequency synthesis, and real world applications. Particular attention will be focused on Phase Locked Loops (PLL's) as frequency synthesizers.
Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
The second of a two-part series on frequency synthesis, with an introduction to Direct Digital Synthesis. We will give a basic review of how a direct digital synthesis system works, touching on the inner workings of the DDS engine at a relatively high level. We will also discuss the tradeoffs between PLL and DDS technology as a base choice for frequency synthesis needs.
Fundamentals of Clocks and Clocking
The webcast covers the fundamentals of clock synthesis and distribution. It covers the various types of phase-locked loops (PLLs), the key features of these devices, and which end market they are designed for. Concepts such as reference switchover, holdover, phase noise, jitter, output drivers, and signal integrity will be covered.
Solutions for Fitting High Performance RF Signal Chains into Small Spaces
This webinar will present the current state of integration of RF IC technology, with a focus on the challenges that non-handset-based wireless equipment designers face as they strive for more functionality in smaller spaces, sometimes with the added headache of having to implement broadband transceivers that can be reused at multiple frequencies.
Fundamentals of the RF Transmission and Reception of Digital Signals
Digital Modulation is an important topic for RF designers because most modern day transceivers transmit and receive digitally modulated data. In this webcast, part of ADI's continuing FUNDAMENTALS OF DESIGN series we will introduce you to the challenges—and solutions—for digital modulation. This webcast is a great way for beginners to get introduced to this vital communications standard or for veteran RF designers learn what's new in the field.
Interfacing RF Components
Few things are as critical to the success to any RF design as the interfacing of the stages within the receiver and transmitter. Harmonics, undesired attenuation, and other deficiencies can manifest themselves in a circuit in which the stages are not properly connected. This webcast will introduce the best practices that will help you get the most out of your RF circuit.
