The functional block diagram of the core is shown in the following figure.

The core consists of two main parts, a Phase Generator and a SIN/COS LUT, which can be used independently or together with an optional dither generator to create a DDS capability. A time-division (TDM) multichannel capability is supported, with independently configurable phase increment and offset parameters.
