Analog Devices AD9954
The AD9954 is a direct digital synthesizer (DDS) featuring a 14-bit DAC operating up to 400 MSPS. The AD9954 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 AD9954 is designed to provide fast frequency hopping and fine tuning resolution (32-bit frequency tuning word).| Part No. | AD9954 |
