how to set AD9102 Configuration Register Values to make continuous sawtooth？

i cannot find the relation between the clock input and the frequency of continuous triangle. As i wanna use 9102 to make continuous triangle，which register is used to set the frequency of triangle? Or which factors would change the frequency?(0027[2:0]=1)

And I have some confusion for the pattern period. When i change 0029[15:0] from 0x1 to 0xFFFF,the triangle has no change.Only 0028[7:4] and  dac gain can affect the waveform of triangle. Any  help would be appreciated.

Here is my resister.(clock=55Mhz)
