Genrerating sine waves at different frequencies with AD9851

I would like to use an AD9851 for generating sine waves from a frequency 1Mhz to 60Mhz. However, from the datasheet of the IC, AD9851 needs to be programmed and conffigured for the matter. I'm intending to use a PIC to control AD9851. I have been confused with the right connexions needed to interface the PIC(p18fxxxx series) with chip.

I would like to be assisted on the connexions required for interfacing the pic and AD9851 and the programming sequence needed. If I could find a program example on how to control AD9851 with a pic using SPI, I would be very glad for that because I'm having trouble understanding the chip.


Thanks in advance,
