GENERAL DESCRIPTION
The AD9835 is a numerically-controlled oscillator employing
a phase accumulator, a COS lookup table, and a 10-bit digital-
to-analog converter integrated on a single CMOS chip. Modu-
lation capabilities are provided for phase modulation and
frequency modulation.
Clock rates of up to 50 MHz are supported. Frequency accuracy
can be controlled to one part in 4 billion. Modulation is effected
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 reduces to 1.75 mW.
This part is available in a 16-lead TSSOP package.
