The AD9833 is a low power programmable generator capable of generating sine, triangle and square wave outputs in types of waveform detection, implementation and time domain reflectometry (TDR) applications that require generation of uniform output frequency and phase. Being software programmable and easily adjustable, no external components are necessary. The frequency register is 28 bits wide: the clock frequency is 25 MHz, enabling 0.1Hz resolution; the AD9833 is clocked at 1 MHz, and can be tuned to 0.004Hz resolution The AD9833 has a standard serial interface that allows the device to interface directly with different microprocessors. The device uses an external serial clock to write data or information to the control device Digitally programmable frequency and phase 12.65 mW 3 V power consumption 0 MHz to 12.5 MHz output frequency range, resolution: 0.1 Hz to 25 MHz reference clock sine, triangle and square wave outputs 2.3 V to 5.5 V power supply No external components required The AD9833 is written via the serial interface line. The serial interface operates at clock frequencies up to 40 MHz and is standard compatible with DSPs and microcontrollers. The device operates from a 2.3 V 5.5 V supply AD9833 has a power-down function (SLEEP). This minimizes power consumption by turning off unused parts of the device, for example the DAC can be turned off while generating the output clock.
