DS856 is a high-speed Direct Digital Synthesizer (DDS) with a frequency tuning resolution of 32 bits, ROM phase resolution of 13-bit and a DAC amplitude resolution of 11 bits. Sine waves in the 1st Nyquist band can be generated up to near 1.6 GHz (at a 3.2-GHz clock rate). The initial phase can be reset to zero degrees to start with.The chip has a pair of complementary outputs with 50-? back terminations. The frequency of output waveforms can be controlled by thirty-two frequency control bits, Vi[0:31].
