Phase Accumulator for Direct Digital Synthesis Resolves to Within 0.7 Hz

Monolithic 32-bit AD9950 features excellent performance from 30 to 130 MHz. Quad logic minimizes memory needs

The AD9950 is a 32-bit phase accumulator designed for direct digital synthesis (DDS) of sine waves at frequencies up to 130 MHz. With an external lookup table and a 10-bit DAC, this monolithic IC forms a system that can synthesize waveforms with 0.7-Hz frequency resolution. Read full article
