Direct Digital Synthesis (DDS)

Direct Digital Synthesis (DDS) is used to produce analog waveforms of different frequencies from a digital signal. It is used for frequency control in wireless systems that must sweep across a wide range. The master frequencies clocks are 5MHz, 16MHz, 16.776MHz, 25MHz, 50MHz, 75MHz, 125MHz, 180MHz, 200MHz, 250MHz, 300MHz, 400MHz, 500MHz, 1GHz, 2.5GHz, and 3GHz with a resolution of 10 b, 12 b, or 14 b.
