TLV320AIC3104: I2C spike on SDA Line

Part Number: TLV320AIC3104

Tool/software:

Hello,

We are getting spikes on SDA line. This spike is present with the TLV320AIC3104 in several completely different layouts. 

It could be related to ACK, but in the second attached picture, the spikes are not always present following the 9th CLK, only in first address and first data.

Is it normal? What is the reason?
