Hi

Sometimes A split frame will appear in the image produced by the camera. Through comparison, it is found that CRC with serial link  detected on 913 is wrong.Error in both directions of data on line.What causes this kind of problem?

    Hi,

    If you can detect the link error, it means the high speed link including signal generating, signal receiver and transmission media could have some design issues.

    pls refer to TI's d/s, it has detailed request on:

    1. 913A's PCLK jitter request, does it catch it in your case?

    2. 913A's PoC design: does it catch the request in d/s or referred to EVM design?

    3. power noise design: what is the ripple?

    4. cable: S11/S21?

    5. connector: s11/s21, and impedance?

    6. what is the receiver?

    for knowledge supporting, you can have some on-line training in www.ti.com/fpd-link website, here one section is on high speed serial link design.

    best regards,

    Steven
