This generator module is made on the basis of a microcircuitAD9850firmsAnalog Deviceswhich is a completeDDS (Direct Digital Synthesis)frequency synthesizer with built-in comparator.

Such synthesizers are unique in their accuracy, practically not subject to temperature drift and aging. Due to its high technical characteristics, DDS synthesizers have recently replaced conventional analog frequency synthesizers. Their main advantage isvery high frequency and phase resolutionwhich are digitally controlled.

You can control the generator both throughconsistent(serial) so and throughparallel interfaces... The digital interface makes it easy to implement microcontroller control.

The AD9850 includes a fast comparator thatsinusoidalDAC output (after external filtering) can be converted torectangularlow-jitter waveform, making it easy to use as a clock driver. Using the potentiometer on the module, you can change the amplitude and hysteresis of these signals.
