Cickey Xu,

25Khz is the maximum SPI sclk freq as guaranteed by Datasheet Spec.

However you can try and increase the freq greater than 25Khz and check your setup. Keep us posted on your results.

Yes the customer can indeed increase Sclk freq to a value greater than 25Mhz and do let us know the result.
