3.5 GSPS直接数字频率合成器, 12位DAC 3.5 GSPS Direct Digital Synthesizer with 12-Bit DAC
Product Details
The AD9914 is a direct digital synthesizer DDS featuring a 12-bit DAC targeted at operating up to 3.5 GSPS. 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 is designed to provide fast frequency hopping and fine tuning resolution 32 bit in standard mode, 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 highly linear swept waveforms of frequency, phase or amplitude. A high speed 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 Absolute Max Ratings table found in the data sheet.
