The outputs of the DDS have 28-bit resolution, so effective frequency steps on the order of 0. Competitive prices from the leading Arbitrary, Direct Digital Synthesis (DDS), Frequency, Signal Arbitrary / Function / Pulse Generators distributor. For now, frequency is limited from 1 to 65535Hz with the minimal step of 1Hz. I built a DDS generator which can be done without a micro-controller at all but normally you'd be using a microcontroller. Even though I need it now and then, I just couldn't seem to justify the cost of one. The DDS sampling frequency was limited to <50 KHz because the sampling rate was 100 KHz. Good news: we found a kit. A DDS generator consists of three major components - a phase accumulator, a sine wave lookup table (usually contained in ROM), and a digital to analog convertor (DAC).

As the signal pass through frequency register and phase register, sample index is counted with clock frequency.
