AD5934:  250 kSPS、12位阻抗转换器网络分析仪

产品详情

AD5934是一款高精度的阻抗转换器系统解决方案,片上集成一个频率发生器和一个12位、250 kSPS模数转换器(ADC)。用频率发生器产生的信号来激励外部复阻抗,外部阻抗的响应信号由片上ADC进行采样,然后由片上DSP进行离散傅里叶变换(DFT)处理。DFT算法在每个频率上返回一个实部(R)数据字和一个虚部(I)数据字。

校准后,使用以下两个公式很容易算出各扫描频率点的阻抗幅度和相应的阻抗相位:

幅度 = √ R2 + I2
相位 = Tan-1 (I/R)

ADI公司还提供一款类似器件AD5933,它是一款2.7 V至5.5 V、1 MSPS、12位阻抗转换器,内置温度传感器,并采用16引脚SSOP封装。

    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.
