AD5933 adaptive clock signal - I2C Baudrate

Hello, Community


In my case, I'm using AD5933 with adaptive Clock Signals to measure lower excitation frequencies. like in these post:


If I wanna measure frequencies below 1000 Hz. My frequency at the MCLK Pin on Ad5933 should be lower than 1 MHz. 

In that case, the system has sometimes communication problems. I figured out that I can solve this problem when I set the I2C Baudrate of the master device further down than 100e3 Bd. 
Could someone explain the reason to me, please? Thank you for your help.
