AD9854ASTZ

AD9854 digital synthesizer is a highly integrated device that uses advanced DDS technology, coupled with two internal high speed, high performance quadrature DACs to form a digitally programmable I and Q synthesizer function. When referenced to an accurate clock source, the AD9854 generates highly stable, frequency-phase, amplitude-programmable sine and cosine outputs that can be used as an agile LO in communications, radar and many other applications. Typical applications include Agile, quadrature LO frequency synthesis, programmable clock generators, FM chirp source for radar and scanning systems, test and measurement equipment, commercial and amateur RF exciters.
