3 V /5 V Pow er S upply                                                T he AD9832 is a numerically controlled oscillator employing

25 MHz S peed  a phase accumulator, a sine look-up table and a 10-bit D/A On-C hip S INE L ook-Up Table             converter integrated on a single CMOS chip. Modulation On-C hip 10-Bit DAC                 capabilities are provided for phase modulation and frequency

S erial L oading                                                                                                               modulation.

^{Pow er-Dow n Option} Clock rates up to 25 MHz are supported. Frequency accuracy ^{45 m W Pow er C onsum ption} can be controlled to one part in 4 billion. Modulation is effected ^{16-L ead TS S OP} by loading registers through the serial interface.

APPL IC ATIONS                                                               A power-down bit allows the user to power down the AD9832

DDS Tuning                                                                        when it is not in use, the power consumption being reduced
