    Tom Johnson16214
    There is no requirement for maximum skew between these clock sources. The only requirement is for frequency coherency. Either one of the clocking solutions proposed will be acceptable. Skew matching is not needed between the SYSCLK and FSYNCCK signals.

    In AIF user's guide, it says:"Both OBSAI and CPRI support inter-TMS320C6474 communication. Control messages for OBSAI and vendor-specific control words for CPRI provide the capability for non-IQ data transfer. " Does this mean the data between DSPs can not be transfered in IQ format？

    Thanks for your answer. And could I understand like this: IQ data can be used for inter DSP communication but we usually do not use them to do so?

    I found the example discribed in sprab58 are implemented on TCI6488, could the example work out on TMS320C6474?

    Sorry to bother you again, in my project, DSP1 transfers data to DSP2 and DSP2 do not redirect these data, so my question is how can I change the code based on sprab58?

    Hi, I have tried the project from http://www.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=sprab58 on C6474, and it works well. In my project, I want DSP1 transfer data to DSP2, but DSP2 do not redirect those data back to DSP1, how can I change the code in the example project?

  • Forum Post: RE: problem about aif on C6474

    Kaiqi Yang
    What I want to do is implement inter-DSP communication without data redirection, that means what DSP1 need to do is to transfer data to DSP2 through AIF and what DSP2 need to do is to receive data from DSP1 and check its correction. So what I want to do seems easier than your project in prab58, and I...

    RandyP: By the way, in section 5.2 of "TMS320C6474 DSP Antenna Interface User's Guide", it refers line rates and data rates of SERDES, what the difference between them. And the data rates lists in the table is theoretical or practical?

    Thanks for your answer! Yes, I use wire to connect JP8 on two TMS320C6474, so timer0 of DSP1 on EVM1 could trigger fsync on EVM2. Is there any possible solution of this problem?
