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.

Some of the schematics in the AD951x data sheets show an LVPECL termination scheme which is different from the classic termination often seen (50 Ω to Vs - 2V, or the Thevenin equivalent thereof). How does this work, and how did you chose 200 Ω for the resistors? Can I use 100 ohms to improve the slew rate (or jitter)?
