Signal Conditioning ADC
Introduction
This DDS device is a numerically controlled oscillator employing a phase accumulator, a sinelook-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 50MHz 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 power-down pin allows external control of a power-down mode. The part is available in a 48-pin TQFP package.
