Description
AD9851 DDS Frequency Function Generator 180M Sine Wave Output Microwave Signal Generator Compatible with 9850
Product Description
The AD9851 is a highly integrated device that uses advanced DDS technology, coupled with an internal high-speed, high-performance D/A converter and comparator, to form a digitally programmable frequency synthesizer and clock generator function. When referring to the accurate clock source, the AD9851 generates a stable frequency and performs a phase-programmable digital analog output sine wave. The sine wave can be used directly as a frequency source or internally converted into a square wave agile clock generator application. AD9851 Innovation The high-speed DDS core accepts 32-bit frequency tuning words, resulting in an output tuning resolution of approximately 0.04 Hz when the system clock is 180 MHz. The AD9851 contains a unique 6 X REFCLK multiplier circuit that eliminates the need for a high-speed reference oscillator. 6 X REFCLK multiplier has minimal effect on SFDR and phase noise characteristics.
