| When using mix-mode and targeting a signal to the second Nyquist zone, it is important to remember that the center frequency chosen in the DPG window is the offset from the DACCLK sample frequency, not 0 Hz. For example, to place the carrier at 1982.5 MHz with a 2.4576 GHz DACCLK as in Figure 12, program the DPG Downloader center frequency to 475 MHz and enable mix-mode. Figure 12 shows the IMD performance of several different DAC output currents and the loss in output power expected with lower currents. | When using mix-mode and targeting a signal to the second Nyquist zone, it is important to remember that the center frequency chosen in the DPG window is the offset from the DACCLK sample frequency, not 0 Hz.
