• RE: AD9958时钟

    From Google translate:

    I recently used ad9958 to do a DDS. Use the microcontroller to the clock signal to sclk. Strangely, the microcontroller to the clock does not receive the AD9958 sclk, the microcontroller output clock signal is normal. But after…

    Hey,

    I have some more questions about the AD9958...

    On my Output Signal I need a Peak to peak Voltage that is variable for example one time i need 5V next time 15V, so I have to change the scale factor for the AM? But how do i calculate the scale factor…

    Hey there,

    I´m looking for a 2 channel dds chip such as the ad9958, but i have some questions.

    Is it possible to generate a difference between the two clock frequencies of both channels, for exapmle by using the internal clock reference and the external…

    AD9958有两路输出,能否让其两路输出分别输出I信号和Q信号。在程序中怎么来实现?

    Hey guys,

    I have one last question about the AD9958, did i get it right that modulation of amplitude, phase or frequency is done by FSK,PSK,ASK?

    So there´s no possibility of using analog modulation such as PM,AM,FM?

    Thanks in regards,

    前段时间做了一个关于AD9958的板子,输出频率在14MHz到22MHz,从其PDF资料上的相位噪声曲线看,15MHz在10KHz以内的杂散非常好,而实际上做出来近端几百Hz的杂散最差的只有80左右的杂散抑制,请问,杂散抑制只能做到这个程度还是我哪个地方没有做好?杂散的位置随着频率的不同而不同,比如在18.185MHz处的杂散主要是250HZ,500Hz;而在18.818MHz处的杂散有30Hz,85Hz和110Hz及其N次谐波的杂散。时钟采用400MHz,对时钟的实现是100MHz晶振通过放大器饱和区取出4次谐波…

    AD9958的两个输出端是否需要上拉?

    现在做AD9958呢 ,写寄存器好多啊,谁有评估板的软件啊,给一个吧!谢谢!

    Hi,

    I would suggest using the AD9958 which has 2 synchronized DDS channels.
