Direct digital synthesis is not the ultimate solution for every application. If you are building an IoT device that you want to enable for both 2.4GHz and 5GHz, you do not need ultra-fast frequency hopping. However, if you are building something that needs to fly though a wide range of frequencies like a chirp source or polar modulator, direct digital synthesis ICs make it easy to integrate.

DDS, or Direct Digital Synthesis, is a form of frequency synthesis. Similarly to PLLs, DDS revolves around creating a broad range of frequencies out of a single fixed frequency oscillator (most often, a stable quartz oscillator). Unlike PLL however, DDS does not use feedback: it is an open-loop circuit, hence the name direct Abstract—A brief overview of Direct Digital Synthesis systems is described as well as the background to some DDS systems and DDS systems in general.
