DIR9001: Synchronization Questions

Part Number: DIR9001
Other Parts Discussed in Thread: DIR1703

Tool/software:

Hi team,

My customer is considering DIR9001.

  1. Are BCKO, LRCKO and DOUT synchronized with the input signal?
  2. Is BFRAME syncrhonized with BCKO?
  3. Are BCKO, LRCKO, DOUT and BFRAME not syncrhonized with external XTI input?

Best regards,

Kazuki Itoh

    Hello,

    The input signal needs to be decoded internally to extract data and clks  and thus there is no synchronization.

    I could not find any indication regarding  synchronization  of  BFRAME and  BCKO in the datasheet ,  but I looked into DIR1703 datasheet which  also has  BFRAME pin with identical  function  and from that datasheet  it seems they are synchronized

    BCKO, LRCKO, DOUT and BFRAME are not synchronized with external XTI input.

    Regards,

    Arash
