25 MHz Direct Digital Synthesizer, Waveform Generator Known Good Die AD9832-KGD FEATURES GENERAL DESCRIPTION 25 MHz speed The AD9832-KGD is a numerically controlled oscillator On-chip SIN lookup table employing a phase accumulator, a sine look-up table, and a 10- On-chip, 10-bit DAC bit digital-to-analog converter (DAC) integrated on a single Serial loading CMOS chip. Modulation capabilities are provided for phase Power-down option modulation and frequency modulation. Temperature range: 40C to +85C Clock rates up to 25 MHz are supported. Frequency accuracy can 200 mW power consumption be controlled to one part in 4 billion. Modulation is effected by Known good die (KGD): these die are fully guaranteed to loading registers through the serial interface. data sheet specifications A power-down bit lets the user power down the AD9832-KGD APPLICATIONS when it is not in use, the power consumption being reduced to Frequency stimulus/waveform generation 5 mW (5 V) or 3 mW (3 V). Frequency phase tuning and modulation Similar DDS products can be found at www.analog.com/DDS. Low power RF/communications systems Additional application and technical information can be found Liquid and gas flow measurement in the AD9832 data sheet.
