AD9361 Reference Clock

Hi,

 

In "AD9361 Reference Clock Requirements_v2.0.pdf" document, recommended reference clock frequency range for AD9361 is 40MHz to 80MHz.

Please guide for the following points:

1. if we use 30.72MHz reference clock, then how it would effect the performance ?

2. Using 40MHz reference clock (as used in reference design), gives better performance, if yes, please explain ?

3. Do we need to use the same clock for the AD9361 and the baseband chip? please explain ?

 

Please guide me for the above concerns.

 

Thanks.
