GE NE RAL DE SCRIPT ION
T his DDS device is a numerically controlled oscillator em-
ploying 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 50 MHz are supported. Frequency accu-
racy can be controlled to one part in 4 billion. Modulation
is effected by loading registers through the parallel micro-
processor interface.
A power-down pin allows external control of a power-down
mode. T he part is available in a 48-pin T QFP package.
