Analog Devices AD9851 CMOS 180 MHz DDS/DAC Synthesizer Datasheet
The AD9851 is a highly integrated device that combines advanced Direct Digital Synthesis (DDS) technology with an internal high-speed, high-performance Digital-to-Analog Converter (DAC) and comparator. It functions as a digitally programmable frequency synthesizer and clock generator, capable of generating stable, phase-programmable digitized analog output sine waves when referenced to an accurate clock source. The device features a 32-bit frequency tuning word for high resolution and includes a unique 6x reference clock multiplier to eliminate the need for a high-speed external reference oscillator.
