AD5933 - Low Frequency External MCLK

Hi all.

We are using a AD5933 for electrical impedance spectroscopy and we are planning to use this device to measure impedances from 0.1Hz to 100kHz.

Using an external MCLK we are able to measure properly down to 3Hz (using a 10kHz external MCLK). Below this frequency the IC seems to freeze as we are not able to communicate with it using the supplied soft (Eval board Eval-AD5933EBZ Rev.C).

Any ideas?

Thanks in advance
