GENERAL DESCRIPTION The AD9914S-CSL is a direct digital synthesizer (DDS) featuring a 12‑bit digital-to-analog converter (DAC).
The AD9914S-CSL 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 1.
4 GHz.
The AD9914S-CSL enables fast frequency hopping and fine tuning resolution (64‑bit capable using programmable modulus mode).
The AD9914S-CSL also offers fast phase and amplitude hopping capability.
The frequency tuning and control words are loaded into the AD9914S-CSL via a serial or parallel input/output port.
The AD9914S-CSL also supports a user d...
