DS856 - High Speed 3GHz Direct Digital Synthesizer
The 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
