• AD1954 master/slave setting

    Hi,

         I want to use the ADC->AD1954 to implement my project.I set the serial interface mode of the ADC  to be master mode and I^2S.So I need to set the serial infterface mode of the AD1954 to be slave mode and I^2S. But I can'f find where to set the…

  • AD9154: DAC PLL not locking

    Dear all,

    we are having trouble setting up the DAC PLL of the AD1954 converter. We have an AC-coupled LVPECL clock at the CLK input pins and perform the following register writes according to the datasheet (e.g. for an input frequency of 500 MHz):

  • How many instructions can be executed per sample in SigmaDSP?

    Calculating IPS (Instructions Per Sample)

    The number of instructions that can be executed per sample depends on three things:

    • The core frequency of the SigmaDSP you are using (as you have it configured in your system)
    • The size of the program memory of…

  • documentation for windnoise algorithm ?

    adau144x lists a windnoise algorithm in sigmadsp.  I did not see any documentation concerning it except for this circa 2002 article related to the ad1954 .

  • Which SPI Mode is used by SigmaDSP Devices?

    The SigmaDSP products (and most devices from Analog Devices with SPI ports) use SPI Mode 3, in which CPOL = 1 and CPHA = 1.

    • CPHA = 1: The data changes on the falling edge of the clock and is read/written on the rising edge of the clock.
    • CPOL = 1: When…

  • RE: Can we bundle SigmaStudio with our product design?

    James,

    The article you have linked to here is for controlling a fixed-function signal flow in the AD1954, the first SigmaDSP IC. SigmaStudio, the current SigmaDSP programming tool, has much more flexibility and many more features for easily programming…

  • RE: Re: EQ Algorithm, Low  shelf wrong!

    Hi Jerald,

    SigmaStudio is a great tool, and coupled with SigmaDSP family of processors makes one of the most friendly, easy to use and powerful DSP platforms for audio applications in the market. I have been using it throughout the years, since it was…

  • RE: USBi Problem

    There is something funny going on with the programming board.

    What is baffeling is that it works sometimes. Does not just go dead

    Below are my personal, random thoughts on what could be going wrong.
