AD9910 as with SI570 as LO

I was thinking of using a SI570 programmable oscillator as replacement

for the 25Mhz crystal eg. used by the AD9910.

 

1) I can use the SI570 as an external oscillator?

2) with the internal muliplier I can reach 1Ghz?

 

3)But since the SI570 is also a DDS with spurs and

  giving a square wave. How would the output

  signal behave according spurs and noise?

 

The overall question is then, is an SI570 usable

for usage in combination with a DDS.
