Overview
The AD9954YSVZ from Analog Devices Inc. is a direct digital synthesizer (DDS) that integrates advanced technology with a high-speed, high-performance DAC to form a complete, digitally programmable, high-frequency synthesizer. This device is capable of generating a frequency-agile analog output sinusoidal waveform up to 160 MHz. It is programmed via a high-speed serial I/O port and includes static RAM to support flexible frequency sweep capabilities in several modes, as well as a user-defined linear sweep mode of operation.
