Description
AD9850 Signal Generator Module DDS Sine Wave Generators Sine Wave Square Wave Adjustable Duty Cycle Waveform Generator
Product Description
The AD9850 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 AD9850 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. The AD9850's innovative high-speed DDS core accepts a 32-bit frequency tuning word. The result is a 0.0291 Hz tuning resolution input that outputs a 125 MHz reference clock.
