Phase noise curves given in the data sheet of AD9914 (Figure 19) show that the internal PLL's Loop Bandwidth is about 30 KHz. But, the loop BW of evaluation board i am testing is about 200 KHz. is it possible to get 30 KHz loop BW when i use internal PLL? Why are the phase noise curves given in data sheet different than i am measuring with 200 KHz loop BW? thank you.
