DAC5688: Read / Write SPI clock Timing

Hi

I have been doing the review of the communication time conditions and I have noticed that there is a minimum period of 100ns (10 MHz) for the SCLK (page 7 datasheet), my question is if that value is correct for the SPI clock or the minimum value of the clock is different?.

In any case, is there the possibility of working with an 8MHz clock?.

Thanks
