Can I get all SPI commands set for HMC778 programming?

I have the datasheet and operating guide documents as the following name. (from the web site)

-. hmc778.pdf

-. 140-00074-00_operating_guide.pdf

Unfortunately, I don't have a HMC778 Evaluation Kit. I want to know how can program the HMC778 using SPI interface when I make my own PCB. Can I get the example of SPI commands set for HMC778?

    I am going to use HMC778 as the following,

    • HMC mode only (not OPEN mode)
    • desired RF output frequency: 10GHz (default) --> its step size can be 100MHz using fractional mode
    • reference & PFD frequency : 30.72MHz
    • charge pump current : 2.5mA (typical)

     

    Reference HW design will be the same structure as evaluation board designed (hmc778lp6c_eval_pcb_schematic.pdf)

     

    Best regards,
