WebFeb 14, 2024 · The DDS produces correctly sampled output waves up to a frequency of 200MHz. However for f > 200 MHz, the output waves are the wrong frequency. For … WebAug 23, 2024 · Setting the phase offset and phase increment values to streaming allows for the output cosine waveform from the DDS Compiler to be directly calculated from the phase input value every cycle. This means the output frequency and phase offset of the output waveform can be changed often and smoothly.
WebDec 3, 2013 · In the DDS Compiler version v6.0, when the non-zero values have been set in the GUI, or the XCO or XCI for programmable Phase Increment or programmable Phase Offset, the output for DDS compiler v6.0 will have different values on all data outputs than DDS compiler v5.0. Solution This is a known issue with DDS Compiler v5.0.
