• RE: no-OS code of AD9379A?

    Hi, I have a new problem!

    I've tried to write the verilog code about spi configuration of the ad9739a evaluation board which has two spi devices (adf4350 and ad9739a). I'm sure that the spi code is working normally because the spi data read from ad9739a…

  • SPI configuration of ADF4350

    Hi, I met a problem when I using the adf4350 on ad9739a evaluation board.

    I've tried to write the verilog code about spi configuration of the ad9739a evaluation board which has two spi devices (adf4350 and ad9739a). I'm sure that the spi code is working…

  • RE: Using the SPI interface on the ADuC 812

    Page 26 of the ADF4350 datasheet indicates how to connect a microcontroller (ADuC7023) to the ADF4350.

    The same diagram can be drawn for ADuC812. A GPIO controls the LE signal of the ADF4350. A second GPIO can be used to control the LE signal of a second…

  • RE: source code for lpc2148

    I have source code available for:

    • ADF4350 Application software in C# .NET
    • ADF4350 Application software in VB6
    • USB microcontroller firmware (this is where the data is actually written to the ADF4350 chip)

    Do you want any of the above?

  • ADF4350 REFin input frequency range.

    Good day.

    Which REFin input frequency range for the ADF4350 synthesizer is correct?
    The table on this page:
    http://www.analog.com/en/rfif-components/pll-synthesizersvcos/products/index.html
    says that Max REFin for ADF4350 is 105 MHz. The same value is mentioned…

  • ADF4350

    Hii there,  I Intend to control the Eval-ADF43500EB1Z through a network connection(using RJ45).  Is it possible to do so?

    How about the graphical PC control source code (Visual Basic or Visual C++ based ) that comes with the ADF4350 Evaluation board.…

  • ADF4350

    I have a customer
    that is doing development of control code for the ADF4350, for a proprietary
    project for his client. He was able to work with the ADF4350 eval board using
    the supplied AD control software. They are working to develop their own
    software to…

  • RE: How do I use the ADF4350 eval board with an Arduino?

    The ADF4350 has a 3-wire SPI interface (CLK, DATA, LE). If your Arduino has an SPI output you could run wires from those pins to the CLK, DATA, and LE testpoints on the ADF4350 board. Remove resistors R51, R52, and R56 to stop the ADF4350 USB microcontroller…

  • RE: ADF4350 VCO core

    The ADF4350 VCO is not a traditional VCO - it is made up of 3 VCO cores; and each core has 16 bands. When a new frequency is programmed, the ADF4350 goes through a calibration process (Band Select) where it finds the correct band for the desired frequency…

  • RE: How much minimum input power required for Reference signal?

    For the ADF4350 reference signal, the minimum power requirement is:

    0.7 Vp-p = 0.35 Vpeak = 0.247 Vrms = 1.225 mW = 0.88 dBm

    For more information, see REFin CHARACTERISTICS in Table…
