GENERAL DESCRIPTION This DDS device is a numerically controlled oscillator employing 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 accuracy can be controlled to one part in 4 billion.
Modulation is effected by loading registers through th...
