i am using AD9912 as Local oscillator,i have operated it in two mode

a) pll bypass mode(1GHz clk from sig gen)

b) pll enable mul=40(25 mhz clk from sig gen).

NB SFDR  difference b/w two case is about 20dB means in case a  NBSFDR is 20 dB more.

is it right or wrong.

what is phase noise specs for 25 MHz clk with multipliyer value=40
