\u00a0 \u00a0 The main purpose of the digital oscillator is the formation of periodic signals of various shapes. Modern digital oscillators based on the direct method of frequency synthesis operate in the range from a fraction of hertz to tens and hundreds of gigahertz. They are used in equipment of different function, replacing it with simple auto-oscillators. At the same time, such oscillators are characterized by all the disadvantages of digital signal processing devices: quantization noise, overlaying of spectra of a digital signal, limited upper working frequency.
\nTherefore, the development of digital oscillators of periodic signals based on the direct method of frequency synthesis using multipliers that would occupy an intermediate position among the known and characterized by a simple and non-expensive implementation scheme is today relevant. The equation of transformation of the process of digital generation of the periodic signal on the basis of the direct method of frequency synthesis is found and the algorithm of the process of digital generation of the periodic signal on the basis of the direct method of frequency synthesis has two conditions: the first condition leads to an increase in phase increase, and the second – to a decrease. A direct method of frequency synthesis for digital generation of a high-frequency periodic signal has been further developed, in which, in contrast to the existing one, clock frequency multiplication is used, which allows to increase the frequency of the output periodic signal by 2\u20134 times. The scheme of the process of digital generation of the periodic signal on the basis of the direct method of frequency synthesis is offered and the description of operation of the digital generator of the periodic signals on the basis of the direct method of frequency synthesis is given. In the Quartus environment the functional scheme of the digital generator of periodic signals on the basis of a direct method of frequency synthesis is developed and investigated. The work of functional blocks included in the digital generator: adder, register, frequency divider, reversing counter, transcoding tables, control circuits, digital-to-analogue converter were investigated. Presenting oscillograms, which confirm the functional capacity of the functional units. Digital part of the circuit of the digital generator is made on the programmable logic devices of the series MAX II EPM1270F256C5. Based on the developed method, a high-frequency digital periodic signal generator based on the FPGA EPM1270F256C5 MAX II series from Intel (Altera) was created, which generates a sinusoidal signal with a frequency value of 0.1 Hz to 32 MHz at a clock frequency of 64 MHz.
