ADIsim Design/Simulation Tools (2)

ADIsimDDS™
The purpose of this tool is to assist a user in selecting and evaluating Analog Devices, Direct Digital Synthesis (DDS) IC's. It allows a user to select a device, enter the desired operating conditions and evaluate it's general performance.
Analog Filter Wizard 2.0
The Analog Filter Wizard™ helps you design a low-pass, high-pass, band-pass or band-stop filter with actual op amps. It then simulates the filter’s performance with these op amps in real time. You can ask the tool to optimize for power, noise, or voltage range, and it will pick op amps and passive components appropriately. Or you can adjust the components manually yourself.

Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
This month we conclude our 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.
Performance Clocks: Demystifying Jitter
Join us as we delve into the realm of sub-picosecond jitter clocks. The relationship between jitter and phase noise will be explored in detail and methods for measuring sub-picosecond jitter and ultra low phase noise will be presented and discussed.
