GENERAL DESCRIPTION

The AD9911 is a complete direct digital synthesizer (DDS). This device includes a high speed DAC with excellent wideband and narrowband spurious-free dynamic range (SFDR) as well as three auxiliary DDS cores without assigned digital-to-analog converters (DACs). These auxiliary channels are used for spur reduction, multitone generation, or test-tone modulation.
