• AD9269 转换错误

    AD9269使用内置的测试码能输出时序正确,但模拟输入无法正确转换,将差分输入短路后,采集的数字信号一直在剧烈变化,且芯片的ORAORB引脚也会经常输出高电平(示波器看到方波),更换了一块芯片后也有同样的问题。

  • AD9269 datasheet, local keyword meaning ?

    Hi,

    In the AD9269 datasheet, referring to the register map section, many bits settings are marked as local.

    What exactly does it mean ? The datasheet doesn't clarify it.

    Could someone give a clear explanation of the local meaning ? 

    Thanks.

  • AD9269 output

    For our next product we look at parts selection. I have a question concerning
    AD9269.
    There is no LVDS Data communication available, only CMOS. We are very worried
    about crosstalk of the digital CMOS lines into our sensitive analog circuitry.…

  • About AD9269 DCOA/DCOB additional jitter performance

  • AD9269 phase difference between channels

    Hello,

    We are using an AD9269 and we have noticed that there is a fixed phase difference between channels A and B.

    Here is a plot of the signal acquisition: the source is the same for both, and the channels polarization network as well:

  • AD9269 Continous programming sequence

    Hello,

    I need to configure an AD9269 via SPI but I am confused about the register order to program.

    The DS and AN877 show that setting the WLEN bits it is possible to set the starting instruction bytes according to the n register accessed, and then each…

  • AD9269调试问题

    谢谢您的解答,现在我自研的板卡上已经可以通过SPI读取到IID 01寄存器 0X75。现在我还没有模拟源,想测试一下芯片是否正常,想配置出一个测试模式 。配置0X0D 值为0X01,但是发现SPI写完之后再去读还是0X00,没配进去,是不是有什么 遗漏要检查的地方。下面是FPGA发送的写波形
