    A Direct Digital Synthesizer (DDS) generates a sinusoidal signal, which is a significant component of many communication systems using modulation schemes. A CORDIC algorithm offers minimum memory requirements compared to look-up-based methods and low latency. The latency depends on the number of iterations, which is determined by the number of angles in the rotation set. However, it is necessary to maintain high spectral purity to optimize the overall system performance. To optimize the opportunity of quantum measurement, low latency and a high spectral purity sine wave generator is essential. The implementation of this design generates output with 64% latency reduction compared to that of the conventional CORDIC design and 72.2 dB SFDR value.
