Direct Digital Synthesizer (DDS) Stuff

Direct Digital Frequency Synthesis has given us a whole new technology of signal generation, modulation and control. PLL frequency synthesizers are therefore becoming ubiquitous. This page provides links to a number of DDS IC manufacturers, DDS Application examples, and to some background theory relating to DDS technology.

Some DDS Theory

Communications: Using Direct Digital Synthesis —This tutorial from Rice University introduces Direct Digital Synthesis with prepared code that transmits arbitrary input as an FM radio signal. The module then explains how to program the DDS hardware and concludes with a simple Frequency Shift Keying exercise.

Martin Pechanec's DDS Page — Includes both DDS theory and a DDS Simulator

Hunt Engineering: Direct Digital Synthesis (DDS) using FPGA

Identifying Sources of Jitter, by Johnnie Hancock, Agilent Technologies. Euro Designcon 2004 paper, October 2004. PDF file, 2.1M. Not strictly DDS, but interesting and has DDS ramifications.
