problem about FS baud rate for ad9789

I am an new user for ad9789. in my design,  FDAC =2400MHz,  FBaud = 120.96MHz,  FDCO = 150MHz, but in fact on the OSC displayer from agilent. FS average frequency is 30.24MHz. FS Pulse high level last for four or five DCO clks,   but when i set Fbaud = 30.24MHz,  FS average frequency is 30.24MHz. FS Pulse high level last for only one DCO clk,. if they all are right. what is the timing sequence for 120.96MHz interface data transfer. how to sample the data of interface by DSC clk. that's all,thank you!
