The AD9833 Has a Standard Serial Interface that Allows the Part to Interface Directly with Several Microprocessors
Frequency Registers are 28 Bits Wide: with 25MHz Clock Rate, AD9833 Can Achieved 0.1Hz Resolution; with 1MHz Clock Rate, AD9833 Can Tuned to 0.004Hz Resolution
The AD9833 Has a Power-Down Function (SLEEP). This Allows Sections of the Device that Are Not Being Used to Be Powered Down, Thus Minimizing the Current Consumption of the Part, e.g., the DAC Can be Powered Down When a Clock Output is Being Generated
The AD9833 is Written to Via a 3-Wire Serial Interface. This Serial Interface Operates at Clock Rates up to 40MHz and is Compatible with DSP and Microcontroller Standards. The Device Uses An External Serial Clock to Write the Data or Control Information Into the Device
AD9833 is a Programmable Waveform Generator Capable of Producing Sine, Triangular, and Square Wave Outputs. Waveform Generation is Required in Various Types of Sensing, Actuation, and Time Domain Reflectometry (TDR) Applications. The Output Frequency and Phase are Software Programmable, Allowing Easy Tuning
