The AD9914BCPZ is a 3.5GSPS Direct Digital Synthesizer with 12-bit DAC. It 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 analogue output sinusoidal waveform at up to 1.4GHz. The AD9914 enables fast frequency hopping and fine tuning resolution (64-bit capable using programmable modulus mode). The DDS also offers fast phase and amplitude hopping capability. The frequency tuning and control words are loaded into the AD9914 via a serial or parallel I/O port. This 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.
