    Thread Summary
    
                The user asked how to configure the AD1937 for 8 kHz sampling frequency. The solution involves disabling the PLL and using Direct Clocking mode with MCLK set to 512 * 8 kHz = 4.096 MHz. Register settings: PLLCC0 = 0x84, PLLCC1 = 0x03. For 192 kHz sampling, the MCLKI pin functionality bits should be set based on the 48 kHz window factor of the desired sample rate, and the PLL clock should be used as the source for both ADC and DAC.

    Hello,
    
 
    I am using AD1937, I need to 8kHz sampling frequency application with AD1937 but first page in the manual  said that it supports 8kHz to 192kHz.
    
 
    But I can't find how to set register to use for 8kHz.
    
 
    How can I set AD1937 to support 8kHz?
    
 
    Thanks.
    
 
    Songhee.
