LMX2594: Sequence for changing frequency

Part Number: LMX2594

I write register in this procedure but doesn't locked.

1. write pll NUM;                        sendCMD(0x2B,0x0001);// PLL_NUM[15:0] 

2. write N;                                    sendCMD(0x24,0x0060);//R36 PLL_N 

3.Program FCAL_EN=1.          sendCMD(0x00,0x2418);// FCAL_EN

Is there something wrong ?
