I have problems with ADF4117. I try to make 100-200mhz PFD 12.5khz form this device.

so I use ADIsimPLL for choose the loop filter's component.(the result in below picture )



and use Int N PLL to provide latch(the result in below picture )



So I got 0x1900 , 0xB541,0x82

I use arduino connect to LE DATA CLK pin and send the command to ADF4117 ( in below picture )



And it's doesn't work . the signal output is not lock . what did I do wrong .
