AD9959:  内置四通道10 bit DAC的500 MSPS直接数字频率合成器

产品详情

产品状态:推荐用于新设计

AD9959由四个直接数字频率合成器(DDS)内核构成,每个通道均可提供独立的频率、相位和幅度控制。这种灵活性可用于校正信号之间由滤波、放大等模拟处理或PCB布局失配而引起的不平衡问题。由于所有通道共享一个公共系统时钟,因此它们具有固有的同步性,支持多个设备的同步。

AD9959可以执行高达16阶的频率、相位或幅度调制(FSK、PSK、ASK)。通过将数据施加到模式引脚,可执行调制。此外,AD9959还支持线性频率、幅度或相位扫描,适合雷达、仪器仪表等应用。

AD9959的串行I/O端口可支持多种配置,提供了极大的灵活性。与ADI公司以往DDS产品中提供的SPI工作模式类似,串行I/O端口提供SPI兼容工作模式,。四个数据引脚(SDIO_0/ SDIO_1/SDIO_2/SDIO_3)对应串行I/O的四种可编程模式,从而提供了灵活性。

AD9959采用高级DDS技术,可在低功耗下提供高性能。这款器件集成了四个具有卓越宽带和窄带SFDR性能的高速10 bit DAC。每个通道均具有专用的32 bit频率调谐字、14 bit相位偏移和10 bit输出比例乘法器。

DAC输出以电源电压为参考源,必须经由电阻或AVDD中心抽头变压器连接到AVDD。每个DAC均具有各自的可编程基准源,用于实现每个通道不同的满量程电流。

当使用REFCLK作为输入,并由DAC提供输出时,这款DDS可用作高分辨率分频器。所有通道共用REFCLK输入源,REFCLK输入源可被直接驱动,或与高达最大值500 MSPS的内置REFCLK乘法器(PLL)配合使用。PLL倍增因数的可编程范围为4~20,步进为整数。REFCLK输入还具有振荡电路,可将外部晶振用作REFCLK源。晶振的频率必须在20 MHz与30 MHz之间。晶振可与REFCLK乘法器配合使用。

AD9959采用节省空间的56引脚LFCSP封装。DDS内核(AVDD和DVDD引脚)采用1.8 V电源供电。数字I/O接口(SPI)在3.3 V电压下工作,并需要将DVDD_I/O(引脚49)连接至3.3 V电压。

AD9959可在-40°C~+85°C的工业温度范围内工作。

    Circuit Note PDF
    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.
