AD9835

The AD9835 is a numerically controlled oscillator employing a phase accumulator, a COS Look-Up Table and a 10-bit D/A converter integrated on a single CMOS chip. Modulation capabilities are provided for phase modulation and frequency modulation.

Clock rates up to 50 MHz are supported. Frequency accuracy can be controlled to one part in 4 billion. Modulation is ef-fected by loading registers through the serial interface. A power-down bit allows the user to power down the AD9835 when it is not in use, the power consumption being reduced to 1.75mW.The part is available in a 16-lead TSSOP package.
