DDS AD9953 output is too low

Hi,

I using AD9953 for a single tone generator.

My circuit is working when i changed clock source from singgle ended PLL to x-tal oscillator.

But output is too low, the output level is -52dBm with -75dBm white noise.

My expectaion is that over -10dBm which is shown in datasheet.

My configuration of resister is that. CFR1=0x00 00 02 00, CFR2=0x00 02 30.

How can i debug my circuit to increase output level?

best regards,

Ryu.
