• AD9854 controller in VHDL

    Hello.

    I have troubles with programming AD9854 DDS through SPI interface. It is necessary to realize a chirp signal generation but first, I decided to try the easiest option — single tone mode of AD9854. There are 80 MHz oscillator and Altera CPLD as…

  • AD9854 Phase Truncation

    Hello, could you confirm that the data sheet for the AD9854 is correct and the 48 bit accumulator is truncated to 17 bits. We are seeing periodic noise on our equipment and the simulations appear to indicate that the accumulator is truncated to 16 bits…

  • Power consumption of AD9854

    Hello,

         I am designing the power circuit for the AD9854 and wanted to know what is maximum current draw for Digital Circuitry Supply Voltage (DVDD) and Analog Circuitry Supply Voltage (AVDD). All I could find was total power consumption, but it isn't…

  • questions about AD9854

    1、Can STM32 drive AD9854?

    2、Is the generated square wave a digital or analog signal?

    3、Can square wave's duty cycle, amplitude and frequency be adjusted?

    4、If it can be adjusted, how much is the dynamic adjustment range of the amplitude? Can it be…

  • AD9854 Labview FPGA control

    I am trying to write a Labview program to control two AD9854's which will generate the signal for AODs in an optical trapping setup. Unfortunately I don't have much experience with Labview so I was wondering if someone already had the VI's to do…

  • 关于AD9854

    您好,以下几个问题,想了解一下:

    1、请问AD9854这款芯片可以用stm32驱动吗?

    2、生成的方波是数字信号还是模拟信号?

    3、生成的方波,其占空比,幅值,以及频率是否可以调整?

    4、如果可以调整,幅值的动态调整范围是多少,能否在±5V之间?

    5、是否可以根据需要,在生成的方波中加入直流信号?

    以上问题,感谢您的解答

  • AD9854-ADRF6701-03 Interface

    Hey Guys,

    You are doing a great work out here.

    However I have a query which I think I'm sure of. But still I am confirming if this can work?

    I have been asked to use AD9854 with ADRF6701-ADRF6703 for this purpose instead of the Up-converter used…

  • Parallel programming AD9854?

    Hi

    I am programming AD9854 through parallel port via FPGA. As an initial test, I intended to generate a single tone sine wave. But, I could'nt.

    Then I decided to just change Updated clock register value and by probing I/O UD see if I could first…

  • AD9854 输出方波

    我用的是ad9854的single-tone模式,输出正弦频率没有问题!但我现在想让其输出方波,应该怎么设置9854呢?

    我照参考电路的示例,将9854的正弦输出接到VINP或者VINN上,但是在VOUT 上没有任何输出!

    请各位专家指点一下,9854如何才能正确输出方波,谢谢!

  • RE: AD9854 SPI programming

    Hi Basil,

    Are you using our evaluation board? If so, if you tristate the CMOS inputs to the AD9854 via the interface buffers, you must drive all the tristated inputs to the AD9854 and not let them float. For instance, master reset, WRB, RDB, S/P input…
