       12.288M --> PLL --> the internal master clock = 24.576M.
       The internal clock for the DACs varies by mode: 512×fs(48kHz

  • RE: What is the full-scale voltage swing of the AD1933/1939 DACs?

    • The full differential voltage swing of the AD1933 DAC, driven with 0 dBFS is 5.6 Vp-p.
    • The single-ended swing is 2.8 V p-p.

    Keep in mind that the AD1934 is the single-ended version of the AD1933.

  • AD1933 & ADAU1372

    Hello Dave,
    Thank you. I have so many questions.
    1. AD1933 datasheet says: AD1933 provides 8 DACs using patented multibit sigmadelta (Σ-Δ) architecture. The DACs include on-board digital reconstruction filters with 70 dB stop-band attenuation, operating…

  • AD1933 default standlone timing operation

    我们产品中准备采用AD1933,8路DAC。根据手册有一些疑惑。

    所有的寄存器都采用复位后的默认设置。MCLK是12.288Mhz。

    1,relation of MCLK BCLK  LRCLK

         after reset, BCLK s is 64 per frame, so BCLK = MCLK/4 = 3.072Mhz,LRCLK = BCLK / 64 = 48K 。

         Is it correct?

    2,default Word Length is 24bit,but LRCLK = BCLK…

  • question about 21489 connect ad1933

    Hello, I want to use AD1933 as slave, it connect with ADSP21489.  In ADSP21489, I use PCGA generate CLK(3.072M) and frame sync clock(48k) to AD1933. And I send a sinusoidal signal, but the AD1933 output pin have not ideal output, it is discontinuous, look…

  • AD1933 DAC generate undesired signal

    Hi,

    I drive a AD1933 in slave mode. The digital input of DAC is connected directly to FPGA. The AD1933 runs in TDM - Mode.

    The AD1933 becomes MCLK (Master Clock: 12,288MHz), BCLK (Bit Clock: 12,288MHz) and DACLRCLK (DAC LEFT RIGHT Clock: 48 kHz) from…

  • RE: AD1933 standalone mode

    Hello neimanAudio,

    No, you cannot use the TDM modes in Standalone mode. Have a look at the application note I wrote a few years ago detailing how to use a small low-cost micro-controller to boot up the codec in TDM mode. It includes the code in the App…

  • RE: Wiring - Multiple DSP boards

    Thanks, Graeme!

    First thing I would suggest is to substitute an ADAU1966 instead of the (2) AD1933. Otherwise, do you have some kind of key to define the letters that are in the circles?

    Regards,

    Coleman
