• AD9633 Measurement

    Hi all,

     

    We bought an AD9633 80MSPS and make a PCB to do the measurement.

    But we find out there are some codes will go wrong on some regular voltage with the 80MHz CLK.

     

     

    (no error In 20 MHz or 40MHz CLK)

    (We didn't use the SPI to change any default…

  • The questions for AD9633

  • AD9633-125

    Can the chip work properly in all four channels at the same time, and the sampling rate of each channel can reach 125M?

  • AD9633 SPI problem

    Hi,

    I am trying to communicate with the AD9633 on the EVAL-AD9633. I basically plugged in the board and connected an external SPI master to the USB_SDI, USB_SCLK, USB_CSB and ISB_SDO pins.

    Using the recommeded jumper connection on J302 (1-2, 4-5 and…

  • AD9633 Over Range Behavior

    Does the AD9633 have any indication of an Over Range / Clip condition?  The behavior that I am seeing is that the ADC code seems to wrap back to zero (using Offset Binary).

  • 关于AD9633的设计

    第一次使用这种类型的ADC,希望ADI公司的技术工程师能帮帮忙。

    目前在设计阶段,遇到以下问题:

    1、数据手册中提到了SYNC引脚,但是该引脚的具体使用方法未明确说明,现在我只使用一片AD9633,请问该SYNC引脚怎么控制?其同步的是什么信号?

    2、当AD9633使用外部参考电压源时,要对VCM引脚处理?
