AD9951:  400 MSPS 14-Bit DAC 1.8 V CMOS Direct Digital Synthesizer

Product Description

The AD9951 is a direct digital synthesizer (DDS) featuring a 14-bit DAC operating up to 400 MSPS. The AD9951 uses advanced DDS technology, coupled with an internal high speed, high performance DAC to form a digitally programmable, complete high frequency synthesizer capable of generating a frequency-agile analog output sinusoidal waveform at up to 200 MHz. The AD9951 is designed to provide fast frequency hopping and fine tuning resolution (32-bit frequency tuning word). The frequency tuning and control words are loaded into the AD9951 via a serial I/O port. The AD9951 is specified to operate over the extended industrial temperature range of –40°C to +105°C.
