Direct Digital Synthesis (DDS)
Analog Devices’ world-leading direct digital synthesis ICs incorporate features such as on-board comparators, RAM, PLLs, mixers, and registers. ADI direct digital synthesis products provide fast acquisition, highly accurate PSK and FSK modulation or high precision tuning resolution, among other benefits. They are an ideal synthesizer solution in applications where precise or agile frequency and phase control is required, such as systems for communications, test equipment, and radar.

Frequently Asked Questions
- Where can I find some good background material on direct digital synthesis?
- Do you have a DDS overview?
- How can I control the envelope of the output?
- What happens if I violate the proper logic level of the reference clock (REF CLK), that is, I underdrive or overdrive it?
- Which option is better for the REF CLK signal: single-ended or differential mode?
