AD9914BCPZ 3.5 GSPS Direct Digital Synthesizer with 12-Bit DAC
AD9914BCPZ Product Overview
The AD9914BCPZ is a high-performance direct digital synthesizer (DDS) from Analog Devices, featuring an integrated 12-bit digital-to-analog converter (DAC). It leverages advanced DDS technology combined with an internal high-speed, high-performance DAC to form a complete, digitally programmable frequency synthesizer.
Capable of generating frequency-agile analog output sinusoidal waveforms at up to 1.4 GHz, the AD9914BCPZ enables fast frequency hopping and fine tuning resolution (64-bit capable using programmable modulus mode). It also offers fast phase and amplitude hopping capability.
