AD9851 DDS Module Programmable Function Generator Digital Frequency Synthesizer Compatible with 9850 Frequency Sweep
Product Description

Chip 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 dig i tal ly programmable frequency synthesizer and clock generator func- tion. When referenced to an accurate clock source, the AD9851 generates a stable frequency and phase-programmable digitized analog output sine wave. This sine wave can be used directly as a frequency source, or internally converted to a square wave for agile-clock generator applications. The AD9851’s innovative high speed DDS core accepts a 32-bit frequency tuning word, which results in an output tuning res o lu tion of approximately 0.04 Hz with a 180 MHz system clock. The AD9851 con tains a unique 6 REFCLK Multiplier circuit that eliminates the need for a high speed reference oscillator. The 6 REFCLK Multiplier has min i mal impact on SFDR and phase noise char- ac ter is tics. The AD9851 provides fi ve bits of programmable phase mod u la tion resolution to enable phase shifting of its output in in cre ments of 11.25°.
