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.

In typical systems, the sample rates will be either 48 kHz, 96 kHz, or 192 kHz. All of these can be achieved in the direct MCLK mode.
However, the upper limit of the sample rate is a little bigger than that. You can see in the datasheet that in 512 Fs direct MCLK mode, the maximum frequency of MCLK is 27.6 MHz. This means that you can actually run the system up to 12% faster than the nominal sample rates, if you wish.
