    Thread Summary
    
                The user is designing a board for impedance spectroscopy using AD5933 and needs to generate a 25kHz MCLK frequency from a 16MHz crystal. The final answer recommends using an external clock divider such as AD9558 or AD9959, controlled via SPI or I2C, or a microcontroller to generate the required MCLK frequency.

    Hello Community,
    
 
    please Help me.
    
 
    First of all sorry, I´m not experienced with it.
    
 
    I´m designing a board for impedance spectroscopy using AD5933.
    
 
    I´d like to change MCLK-frequencies to be able to measure lower frequencies with AD5933. If it's possible with a programmable solution I would be very happy.
    
 
    The following table is a part of manual UG-364. I need frequencies down to 25 kHz at MCLK-Pin of AD5933. 
    
 
     
    
 
    
 
    Could you recommend me some solutions, please? I´d like to use IC´s and don't wanna spending many hours to design filters and so on. Thank you.
