Interfacing ADF4350 Eval Board with Arduino MEGA 2560

I have a project which needs ADF4350 Evaluation Board configured to give frequency sweep from 2 GHz to 3 GHz.

The ADF4350 has 3 wire SPI Protocol for serial communication.

Are there any libraries related to ADF4350 for arduino board for SPI communication?

Also I need some help reducing the clock speed of SPI to 50 KHz from its max. speed taken inbuilt.

I have attached the datasheet ADF4350 IC.

Please reply ASAP. Thank you! :confused:
