ANALOG DEVICES AD9911BCPZ Direct Digital Synthesizer, 10-Bit DAC, 500 MSPS, 1.71 to 1.89 V, -40 to 85 Deg C, LFCSP-EP-56

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-analogue converters (DACs). These auxiliary channels are used for spur reduction, multitone generation, or test-tone modulation. It is the first DDS to incorporate SpurKiller technology and multitone generation capability. Multitone mode enables the generation upto four concurrent carriers; frequency, phase and amplitude can be independently programmed. Multitone generation can be used for system tests, such as inter-modulation distortion and receiver blocker sensitivity. It is used in application such as agile local oscillator, test and measurement equipment, commercial and amateur radio exciter, radar and sonar, test-tone generation, fast frequency hopping, clock generation etc.
