产品详情

产品状态:推荐用于新设计

AD9910是一款内置14 bit DAC的直接数字频率合成器(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。

用户可以访问三个用于控制DDS的信号控制参数,包括:频率、相位与幅度。AD9910利用32 bit累加器提供快速跳频和频率调谐分辨率。在1 GSPS采样速率下,调谐分辨率为~0.23 Hz。这款DDS还实现了快速相位与幅度切换功能。

用户可通过串行I/O端口对AD9910的内部控制寄存器进行编程,以实现对AD9910的控制。AD9910集成了静态RAM,可支持频率、相位和/或幅度调制的多种组合。AD9910还支持用户定义的数控数字斜波工作模式。在这个模式下,频率、相位或幅度随时间呈线性变化。AD9910内置的高速并行数据输入端口能实现频率、相位、幅度或极点的直接调制,以支持更高级的调制功能。

AD9910可在扩展的工业温度范围内工作(欲了解更多信息,请参考数据手册的绝对最大额定值部分)。

    高性能时钟: 解密抖动
    现在每个电子设备一般都有多个时钟,所以必须考虑到这些时钟的抖动性能。低抖动和低相位噪声的时钟对数字信号的处理是非常重要的。所谓时钟抖动是指时钟触发沿的随机误差,通常可以用两个或多个时钟周期之间的差值来量度,这个误差是由时钟发生器内部产生的。时钟的抖动将会影响到仪表的精确测量,在无线通信中将会引起更高的误码率和不良的通信质量,时钟的相位噪声也会引起数据误差和降低数据吞吐量。因此,欢迎大家和我们一起探讨亚皮秒抖动的时钟性能。在这次在线研讨会上,我们将详细探讨抖动和相位噪声的关系以及亚皮秒抖动和超低相位噪声的测量方法。这次在线研讨会还将会涵盖高性能时钟IC的应用考虑。ADI公司的新型ADIsimCLK时钟仿真工具的使用也将会在这次研讨会上作详细介绍。

    Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
    This month we conclude our two-part series on frequency synthesis, with an introduction to Direct Digital Synthesis. We will give a basic review of how a direct digital synthesis system works, touching on the inner workings of the DDS engine at a relatively high level. We will also discuss the tradeoffs between PLL and DDS technology as a base choice for frequency synthesis needs.
