AD9852ASVZ Datasheet PDF - ADI

●The AD9852 series Digital Synthesizer which is highly integrated device that uses advanced DDS technology, coupled with an internal high speed, high performance digital-to-analog converter (DAC) to form a digitally programmable, agile synthesizer function. When referenced to an accurate clock source, the AD9852 generates a highly stable frequency-, phase- and amplitude-programmable cosine output that can be used as an agile LO in communications, radar and many other applications. The innovative high speed DDS core of the AD9852 provides 48-bit frequency resolution (1µHz tuning resolution with 300MHz SYSCLK). Maintaining 17bits ensures excellent SFDR.
