GENERAL DESCRIPTION
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 1.75 mW.
The part is available in a 16-lead TSSOP package.
