The AD9833 has a standard serial interface that allows the device to interact directly with different microprocessors. The device uses an external serial clock to write data or information to the control device The AD9833 is a low-power programmable generator capable of generating sinusoidal, triangular, and square outputs in various types of time domain reflectometry (TDR) detection, implementation and reflectometry applications in ways that require uniform frequency and output phase generation. Being software programmable and easily adjustable, no external components are needed. The frequency register has 28 bits of : clock frequency is 25 MHz, allowing for a resolution of 0.1 Hz; the AD9833 has a frequency of 1 MHz and can be tuned to a resolution of 0.004 Hz Digitally programmable frequency and phase 12.65 mW 3 V power consumption Output frequency range from 0 MHz to 12.5 MHz, resolution: 0.1 Hz to 25 MHz Reference clock Sinusoidal, triangular and square outputs 2.3 V to 5.5 V power supply No external components required The AD9833 is written through the serial interface line. The serial interface operates at clock frequencies up to 40 MHz and is standard compatible with and microcontrollers. The device is powered by a 2.3 V and 5.5 V power supply, Weight: 0.00661386786 pounds, Manufacturer: Rtxbvg
