What is the difference between 250MHz target clk, 250Msps vs …

WebThe ADC clock is set at 1 MHz, by prescaling the system clock (16 MHz) by 16. Since every conversion takes approximately13 clocks at full scale, conversions can be achieved at a frequency of 1/13 = 0.076 MHz = 76 KHz. The sampling frequency should be significantly lower than 76 KHz to let the ADC have the time to sample the data. WebThe FFT returns a two-sided spectrum in complex form (real and imaginary parts), which you must scale and convert to polar form to obtain magnitude and phase. The frequency axis is identical to that of the two-sided power spectrum. The amplitude of the FFT is related to the number of points in the time-domain signal.

WebThis is what the FFT gives you. For example, if you sum sin (2*pi*10x)+sin (2*pi*15x)+sin (2*pi*20x)+sin (2*pi*25x), you probably want to detect the "frequency" as 5 (take a look at the graph of this function). However, the FFT of this signal will detect the magnitude of 0 for the frequency 5. WebTo get a clock rate of 125 MHz, in the DAC tab, set the Samples per clock cycle parameter to 2. Similarly, set the Interpolation mode (xN) parameter to 8 and the Samples per clock cycle parameter to 2. These settings imply that the Stream clock frequency is 2000/(8 x 2) = 125 MHz.
