Abstract
A direct digital synthesis (DDS) device includes a first digital to analog converter (DAC) and a second DAC, wherein the first and second DACs are configured to respectively process first and second samples of a digital amplitude signal. The DDS device also includes a switch configured to receive first and second DAC output signals from the first and second DACs, respectively, and selectively switch among at least the first DAC output signal and the second DAC output signal to generate a combined signal. The DDS device also includes a signal mixer configured to receive the combined signal and a mixer clock signal, wherein the signal mixer is a multi-mode mixer further configured to operate in (i) a pass-through mode where the combined signal is provided as a mixed signal, and (ii) a mixing mode where the combined signal is mixed with the mixer clock signal, to generate the mixed signal.
