The AD9915/PCBZ is an Evaluation Board 2.5 GSPS Direct Digital Synthesizer with 12-Bit DAC. The AD9915 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 1.0 GHz. The AD9915 enables fast frequency hopping and fine tuning resolution (64-bit capable using programmable modulus mode). The AD9915 also offers fast phase and amplitude hopping capability. The frequency tuning and control words are loaded into the AD9915 via a serial or parallel I/O port. The AD9915 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.
