• Please tell me the practicable range of the AD9634 LVDS interface.

    I read AD9634 datasheet.

    In Figure 55. Differential LVDS Sample Clock (Up to 625 MHz), AD9634 is recever and AD9511 driver.

    AD9511 Differential Output Voltage 250mV - 450mV.

    AD9634 Differential clock input 300mV - 3.6V.

    When AD9511 output 250mV, would…

  • AD9707 outputs nothing

    Hello,

    We're having some trouble with an AD9707. We're clocking it at 122.88MHz from a LVPECL output of an AD9511 that should meet differential clock level specifications of AD9707 and we've checked that it does. We're using a ramp generator as data…

  • Eval board software

    I have an old eval board and wanted to know if there have been any updates to the software.  Where can I get a copy of your latest EVB software for the AD9511?

  • RE: ADF4355-2 close-in frequency independent spur problem

    Yes there is a way, the clock distributor is outputting LVPECL 1600mV and it can be increased to LVPECL 2000mV. Will try it. That is for ADF4355 references, which are LVPECL differential AC-coupled.

    I have tried to sniff the PCB with a crude DIY E-field…

  • RE: My PLL is occasionally losing lock.  Why?

    There are a variety of causes of why a PLL will occasionally lose lock.

    This answer assumes that the user is able to make their PLL lock, but it doens't stay locked.

    The most common causes are:

    1. Poor power and/or signal connections. Be sure that…

  • ADI针对电子测试和测量的RF和微波解决方案,优势在哪?

    RF和微波IC广泛用于电子测试和测量仪器,比如频谱分析仪、网络分析仪、信号发生器和通信测试仪。当无线通信在我们的生活中变得越来越普及,比如4G/5G和物联网,对于它们的测试基准的要求也在不断提高。在ADI针对电子测试和测量的RF和微波解决方案中,重点讨论ADI产品如何融入相关信号链。

    主要挑战和系统设计考虑


    宽动态范围

    最小化RF测试台的噪底(比如相位噪声)对于保持宽动态范围内的测试信号纯度很重要。但是,更多的数字信号处理任务将增加辐射噪声,因此获得干净的信号是个难题。

    宽带宽

  • Hardware Interfacing of AD9211 Control Pins

    In datasheet of AD9211(attached below), on page No.23, it is written that "All serial pins(SCLK/DFS, SDIO/DCS) are inputs with an open-drain configuration and should be tied to an external pull-up or pull-down resistor (suggested value of 10 kΩ)".…

  • 【在线研讨会讲义PPT下载】从0Hz到110GHz的全频谱RF信号链

    此次在线研讨会阐释了自收购Hittite Microwave后ADI的全新及扩展的RF能力。我们会举例说明ADI涵盖的更宽频谱范围及其真DC的重要性。信号链外的性能同样至关重要,展示低噪声、高稳定性控制和电源元件如何改善总体RF信号性能,并将讨论完整的信号链示例。

    主要讨论天线到比特和比特到天线,信号链覆盖,即刚才提到的从真正的DC 0 Hz到110 GHz的频谱覆盖。 我会简要介绍其中涉及到的各类设备。
