AD9910是一款内置14 bit DAC的直接
Digital frequency synthesizers（DDS），支持高达1 GSPS的采样速率。AD9910采用高级DDS专利技术，在不牺牲性能的前提下可极大降低功耗。DDS/DAC组合构成数字可编程的高频模拟输出频率合成器，能够在高达400 MHz的频率下生成频率捷变正弦波形。
Users can access three signal control parameters for controlling the DDS, including: frequency, phase, and amplitude. The AD9910 utilizes a 32-bit accumulator to provide fast frequency hopping and frequency-tuning resolution. At a 1 GSPS sample rate, the tuning resolution is ~0.23 Hz. The DDS also implements fast phase and amplitude switching.
The AD9910's internal control registers can be programmed via serial I/O ports to control the AD9910. The AD9910 integrates static RAM to support multiple combinations of frequency, phase, and/or amplitude modulation. The AD9910 also supports user-defined CNC digital oblique operating modes. In this mode, the frequency, phase, or amplitude changes linearly over time. The AD9910's built-in high-speed parallel data input port enables direct modulation of frequency, phase, amplitude, or pole to support more advanced modulation capabilities.
The AD9910 operates over an extended industrial temperature range (see the Absolute Maximum Ratings section of the datasheet for more information).
