The AD9914 is a direct digital synthesizer (DDS) featuring a 12‑bit DAC. The AD9914 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 AD9914 enables fast frequency hopping and fine tuning resolution (64‑bit capable using programmable modulus mode). The AD9914 also offers fast phase and amplitude hopping capability. The frequency tuning and control words are loaded into the AD9914 via a serial or parallel input/output port.
The AD9914 also supports a user defined linear sweep mode of operation for generating linear swept waveforms of frequency, phase, or amplitude. A high speed, 32-bit parallel data input port is included, enabling high data rates for polar modulation schemes and fast reprogramming of the phase, frequency, and amplitude tuning words.
The AD9914 is specified to operate over the extended industrial temperature range (see the Absolute Maximum Ratings section in the data sheet).
