The adf4106 is a 6GHz !!! PLL Frequency Synthesizer. Are you going to build a PIC based mobile telephone?

Please be more specific in your questions. Tell us WHY you need a prescaler and what frequencies you are thinking about (input and output). Do you need a fixed prescaler or an adjustable one? etc., etc.
The more info you can give us, the better the answers will be.
