HELLO,recently i am using AD9914 to generate a linear sweep,from 0.1GHZ to 1.1GHZ,the step frequency is 1KHZ,and the step time is 1ns,but when i see the datasheet and from the Δt = 24P/fsys,is that means if the sys_clock is 3.5G,so the minimum step time is about 6.8ns?if it's true,how can i realize my purpose of 1ns step time?

thank you .
