AD9833 DDS 0-12.5 MHz Signal Generator Module
The AD9833 DDS 0-12.5 MHz Signal Generator Module is a programmable waveform generator capable of generating 0-12.5 MHz sine, triangle, and square wave signals. Waveform generators are widely used in various measurement, excitation, and time domain applications. The output frequency and phase are programmable and easily adjustable via software. A 25 MHz clock is used, with a precision of 0.1 Hz. The clock frequency is 1 MHz, and the precision can reach 0.004 Hz. Three serial interfaces are used to write data.
