• AD9545参考监视出现异常

    您好!我在官方AD9545开发板上试验AD9545锁定GPS秒脉冲时发现:循环断开外部参考信号时参考故障会出现异常。

    过程描述:我将给开发板REFB_N接1PPS参考时发现ACE界面持续显示参考无效(大概十分钟),0X3008寄存器为0X08。用示波器在AD9545开发板R305上可以测得信号。后来通过ACE复位后正常,反复测试(在REFB_N SMA接口上拧上带有1PPS信号的线缆发现指示有效后再拧下线缆)发现当有几率出现异常情况。出现异常后如果不复位则0X3008寄存器为0X08,无法恢复正常…

  • Questions about the accuracy of the AD9545

    Hello
    I have a question regarding the accuracy of the AD9545.

    For example, what is the accuracy of the output frequency of 0.2ppm TCXO corrected by 0.1ppm 1pps?
    Will it be output with an accuracy of 1 pps?

    I would appreciate it if you could reply.
