A problem about AD9854

Hi, I have troubles when I use the chip AD9854.

I want to use AD9854 to generate a chirp signal with a bandwidth of 20(10)MHZ.

I want the chirp signal’s time period T as small as possible.

So I want to know what the minimum value of the chirp time period T is.

I can’t understand what the datasheet says, and please give me the result of the minimum time period when the bandwidth is 20MHZ and 10 MHZ.

Thanks very much!
