Other Parts Discussed in Thread: UCD3138A
Hi Champ,
I am asking for my customer. They are using UCD3138128A as the slave.
We measured that there are two-stage slope on the rise time of SCL signal, the waveform is shown as below pic. (no added I2C buffer)
Though, currently the data is receiving all correctly.
The customer would still have a concern of causing problems in the interpretation of the data. Is there a slight possibility that it caused a communication error?
Also, what makes it there are two-stage slope ? How to effectively find the root cause of it ?
I suppose the issue relates to the customer's hardware, is there any other possibility ?
Thanks for any reply.
Best Regard.
