AD9915BCPZ Datasheet PDF - ADI

The AD9915BCPZ is a Direct Digital Synthesizer (DDS) featuring a 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 analog output sinusoidal waveform at up to 1.0GHz. 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 input/output port. The AD9915 also supports a user defined linear sweep mode of operation for generating linear swept waveforms of frequency, phase or amplitude.
