• SDRAM Timing

    Hello,
    i am using an ADSP-BF523 and an Elite SDRAM M12L64164A-5BIG2Y.
    The external busclock is 100MHz and the SDRAM-Timings are:
    *pEBIU_SDRRC = 0x612;
    *pEBIU_SDBCTL = EBCAW_8 | EBSZ_16 | EBE;
    *pEBIU_SDGCTL = PSS | TWR_2 | TRCD_2 | TRP_2 | TRAS_6 | CL_2 |…

  • RE: Low Volume Level at output of BF537

    I'm using the analogue output on the dScope to generate a 0dBu sinewave. This is being fed into one channel of the BF537 via the AD1854. I'm then using the simple C_Talkthrough_I2S.dpj to pass the encoded signal straight back into the DAC(AD1854…

    Joao,

     

    You mentioned SCLK = 150Mhz, is that a typo or is it really 150? If its true, you are definitely over clocking the system (it can't be more than 133). Please refer to "Table 17. ADSP-BF523/ADSP-BF525/ADSP-BF527 Processors Maximum SCLK…
