AD9914BCPZ

Overview

The AD9914BCPZ is a direct digital synthesizer (DDS) featuring an integrated 12-bit DAC. It operates with a 3.5 GSPS internal clock speed and generates frequency-agile analog output sinusoidal waveforms up to 1.4 GHz. The device provides a frequency tuning resolution of 190 pHz, a 16-bit phase tuning resolution, and 12-bit amplitude scaling. It supports programmable modulus for 64-bit fine-tuning capability and includes automatic linear and nonlinear frequency sweeping. The component utilizes a 32-bit parallel datapath interface and offers serial or parallel I/O control. It functions on 1.8 V and 3.3 V power supplies within the extended industrial temperature range.
