DS90UB953-Q1: IIC report errors

user5006961

HI sir:

I use UD90UB953+954 design.

At this time, the signal transmitting the graph is normal, and the graph can be displayed.
However, when configuring the image effect, a probabilistic IIC error occurs without an ACK.

What caused this, or did I have a problem setting the parameters

Hello,
Please check your PoC filter. It may be not good enough for the lower frequencies for Back channel .

954 will not send ACK to the MCU if it did not receive ACK from the Imager or Serializer.
