Hi
Could you please refer the attached file(issue waveform)
Customer found the overshoot on SCL/SDA signals. They have to improve it, because it is over IC's ABS.
Could you please give me your advice for improvement.

Hi Bobby-san
Thank you for your advice.
Wire length : 105mm.
Customer will try to modify their circuit from your advice.
Hey Muk,
The series resistance of 100 ohms will shift the VoL (recall VoL = (Rseries+Ron) *IoL) so we may want to try 50 ohms and 200pF instead. This should give you the same affect and lower the VoL.
Thanks,
-Bobby
