How can I adjust the AD9102 SAWTOOTH output frequency

Hi:

thanks for your reply.

But,I find when I adjust Digital Gain or SAW_STEPx to alter output frequency,the equally DAC resolution is decreased form 14 bit to 7 bit when the output is about 200khz.How can I get a 2 Vpp and 200khz triangular wave with high resolution?or other IC?
