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.
