GE NE RAL DE SCRIPT ION
T his DDS device is a numerically controlled oscillator employ-
ing a phase accumulator, a sine 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 25 MHz are supported. Frequency accuracy
can be controlled to one part in 4 billion. Modulation is effected
by loading registers through the parallel microprocessor
interface.
A powerdown pin allows external control of a powerdown
mode. T he part is available in a 48-pin T QFP package.
